Minox Contax Racetrack Playa

Racetrack Playa in Death Valley National Park.

For most of the year Racetrack Playa in Death Valley, California is a dry lake, a completely flat expanse of cracked white clay. There are a few scattered stones on the surface, from a handful of centimetres in diameter to half a metre. Some of the stones have trails hundreds of metres long displaying that they have moved across the ground – but how?

Nobody has noticed 1 in motion, but geologists have tracked the stones progress for years, usually in March.

The most likely explanation entails the spring weather. Rain and melting snow from the surrounding hills leaves a lot of of the rocks partly-submerged in enormous, shallow pools. As temperatures fall at evening, ice can form a collar around the base of a rock. This creates enough buoyancy for strong winds to overcome friction with the lake bed. This is only possible simply because of the flatness of the Playa, which allows wind to gust at 90 mph close to the ground.

In any case, the movement probably on lasts less than a minute and might only happen every many years. This is probably why the sailing stones of Racetrack Playa have remained a single of the world’s more elusive climate phenomena.

Steven F. Udvar-Hazy Center: Space exhibit panorama (Space Shuttle Enterprise)

Image by Chris Devers
See much more photographs of this, and the Wikipedia write-up.

Specifics, quoting from Smithsonian National Air and Space Museum | Space Shuttle Enterprise:

Manufacturer:
Rockwell International Corporation

Nation of Origin:
United States of America

Dimensions:
Overall: 57 ft. tall x 122 ft. long x 78 ft. wing span, 150,000 lb.
(1737.36 x 3718.57 x 2377.44cm, 68039.6kg)

Supplies:
Aluminum airframe and physique with some fiberglass functions payload bay doors are graphite epoxy composite thermal tiles are simulated (polyurethane foam) except for test samples of actual tiles and thermal blankets.

The initial Space Shuttle orbiter, &quotEnterprise,&quot is a complete-scale test vehicle employed for flights in the atmosphere and tests on the ground it is not equipped for spaceflight. Though the airframe and flight control elements are like those of the Shuttles flown in space, this car has no propulsion system and only simulated thermal tiles due to the fact these functions were not necessary for atmospheric and ground tests. &quotEnterprise&quot was rolled out at Rockwell International’s assembly facility in Palmdale, California, in 1976. In 1977, it entered service for a nine-month-long strategy-and-landing test flight system. Thereafter it was employed for vibration tests and fit checks at NASA centers, and it also appeared in the 1983 Paris Air Show and the 1984 World’s Fair in New Orleans. In 1985, NASA transferred &quotEnterprise&quot to the Smithsonian Institution’s National Air and Space Museum.

Quoting from Wikipedia | Space Shuttle Enterprise:

The Space Shuttle Enterprise (NASA Orbiter Vehicle Designation: OV-101) was the very first Space Shuttle orbiter. It was constructed for NASA as part of the Space Shuttle system to perform test flights in the atmosphere. It was constructed with out engines or a functional heat shield, and was for that reason not capable of spaceflight.

Initially, Enterprise had been intended to be refitted for orbital flight, which would have made it the second space shuttle to fly after Columbia. However, in the course of the building of Columbia, particulars of the final design changed, specifically with regard to the weight of the fuselage and wings. Refitting Enterprise for spaceflight would have involved dismantling the orbiter and returning the sections to subcontractors across the country. As this was an costly proposition, it was determined to be less expensive to construct Challenger about a body frame (STA-099) that had been created as a test article. Similarly, Enterprise was deemed for refit to replace Challenger soon after the latter was destroyed, but Endeavour was built from structural spares as an alternative.

Service

Construction started on the first orbiter on June 4, 1974. Designated OV-101, it was initially planned to be named Constitution and unveiled on Constitution Day, September 17, 1976. A create-in campaign by Trekkies to President Gerald Ford asked that the orbiter be named after the Starship Enterprise, featured on the tv show Star Trek. Even though Ford did not mention the campaign, the president—who for the duration of Planet War II had served on the aircraft carrier USS&nbspMonterey&nbsp(CVL-26) that served with USS&nbspEnterprise&nbsp(CV-6)—said that he was &quotpartial to the name&quot and overrode NASA officials.

The design of OV-101 was not the identical as that planned for OV-102, the 1st flight model the tail was constructed differently, and it did not have the interfaces to mount OMS pods. A huge quantity of subsystems—ranging from major engines to radar equipment—were not installed on this car, but the capacity to add them in the future was retained. Alternatively of a thermal protection system, its surface was mainly fiberglass.

In mid-1976, the orbiter was utilized for ground vibration tests, permitting engineers to examine information from an actual flight car with theoretical models.

On September 17, 1976, Enterprise was rolled out of Rockwell’s plant at Palmdale, California. In recognition of its fictional namesake, Star Trek creator Gene Roddenberry and most of the principal cast of the original series of Star Trek have been on hand at the dedication ceremony.

Approach and landing tests (ALT)

Main write-up: Method and Landing Tests

On January 31, 1977, it was taken by road to Dryden Flight Research Center at Edwards Air Force Base, to begin operational testing.

Even though at NASA Dryden, Enterprise was used by NASA for a assortment of ground and flight tests intended to validate aspects of the shuttle plan. The initial nine-month testing period was referred to by the acronym ALT, for &quotApproach and Landing Test&quot. These tests included a maiden &quotflight&quot on February 18, 1977 atop a Boeing 747 Shuttle Carrier Aircraft (SCA) to measure structural loads and ground handling and braking qualities of the mated program. Ground tests of all orbiter subsystems have been carried out to confirm functionality prior to atmospheric flight.

The mated Enterprise/SCA mixture was then subjected to five test flights with Enterprise unmanned and unactivated. The objective of these test flights was to measure the flight traits of the mated combination. These tests had been followed with 3 test flights with Enterprise manned to test the shuttle flight control systems.

Enterprise underwent 5 totally free flights exactly where the craft separated from the SCA and was landed beneath astronaut handle. These tests verified the flight characteristics of the orbiter design and were carried out below several aerodynamic and weight configurations. On the fifth and final glider flight, pilot-induced oscillation problems had been revealed, which had to be addressed just before the 1st orbital launch occurred.

On August 12, 1977, the space shuttle Enterprise flew on its own for the 1st time.

Preparation for STS-1

Following the ALT system, Enterprise was ferried amongst several NASA facilities to configure the craft for vibration testing. In June 1979, it was mated with an external tank and solid rocket boosters (recognized as a boilerplate configuration) and tested in a launch configuration at Kennedy Space Center Launch Pad 39A.

Retirement

With the completion of crucial testing, Enterprise was partially disassembled to allow specific elements to be reused in other shuttles, then underwent an international tour visiting France, Germany, Italy, the United Kingdom, Canada, and the U.S. states of California, Alabama, and Louisiana (for the duration of the 1984 Louisiana Planet Exposition). It was also utilised to fit-verify the in no way-utilized shuttle launch pad at Vandenberg AFB, California. Finally, on November 18, 1985, Enterprise was ferried to Washington, D.C., where it became property of the Smithsonian Institution.

Post-Challenger

Soon after the Challenger disaster, NASA deemed using Enterprise as a replacement. Nevertheless refitting the shuttle with all of the required gear needed for it to be employed in space was considered, but as an alternative it was decided to use spares constructed at the same time as Discovery and Atlantis to develop Endeavour.

Post-Columbia

In 2003, following the breakup of Columbia in the course of re-entry, the Columbia Accident Investigation Board performed tests at Southwest Analysis Institute, which employed an air gun to shoot foam blocks of equivalent size, mass and speed to that which struck Columbia at a test structure which mechanically replicated the orbiter wing leading edge. They removed a fiberglass panel from Enterprise’s wing to carry out analysis of the material and attached it to the test structure, then shot a foam block at it. Although the panel was not broken as a outcome of the test, the effect was sufficient to permanently deform a seal. As the reinforced carbon-carbon (RCC) panel on Columbia was 2.five occasions weaker, this recommended that the RCC top edge would have been shattered. Extra tests on the fiberglass were canceled in order not to risk damaging the test apparatus, and a panel from Discovery was tested to determine the effects of the foam on a similarly-aged RCC top edge. On July 7, 2003, a foam effect test designed a hole 41&nbspcm by 42.five&nbspcm (16.1&nbspinches by 16.7&nbspinches) in the protective RCC panel. The tests clearly demonstrated that a foam effect of the type Columbia sustained could seriously breach the protective RCC panels on the wing leading edge.

The board determined that the probable lead to of the accident was that the foam effect brought on a breach of a reinforced carbon-carbon panel along the leading edge of Columbia’s left wing, allowing hot gases generated for the duration of re-entry to enter the wing and cause structural collapse. This caused Columbia to spin out of control, breaking up with the loss of the entire crew.

Museum exhibit

Enterprise was stored at the Smithsonian’s hangar at Washington Dulles International Airport before it was restored and moved to the newly built Smithsonian’s National Air and Space Museum‘s Steven F. Udvar-Hazy Center at Dulles International Airport, where it has been the centerpiece of the space collection. On April 12, 2011, NASA announced that Space Shuttle Discovery, the most traveled orbiter in the fleet, will be added to the collection after the Shuttle fleet is retired. When that happens, Enterprise will be moved to the Intrepid Sea-Air-Space Museum in New York City, to a newly constructed hangar adjacent to the museum. In preparation for the anticipated relocation, engineers evaluated the car in early 2010 and determined that it was secure to fly on the Shuttle Carrier Aircraft when once more.

The Sad Dragonfly.

Image by Hammonton Photography
Rest in Peace, Sad Dragonfly.
&gtFor these of you who do not know a lot about dragonflies here is my &quotSad Dragonfly&quot story from nowadays &amp a few facts. ♥ I love dragonflies… &amp nicely, bugs!

&gtWhen I discovered him he was struggling, sad, &amp broken.. literally.
He had just gotten in a fight with another male dragonfly, probably more than a mate or lunch. When male dragonflies fight generally it is until the death, they grab the other’s wings &amp twist – &amp rip them off.
&gtDragonflies have six legs, but they cannot stroll. They can only fly or land. Strange. Nevertheless, when dragonflies fight &amp shed- they can no longer survive.

I found &quotThe Sad Dragonfly&quot today in my field. I was trying to figure out what was incorrect with him, and then I saw his wings had been torn. He could not walk, so he was just kind of flapping his wings &amp not moving very far. Then I remembered that dragonflies cannot walk, and I felt the require to step in.

When I see an insect suffering/dying normally I move it to a secure location, that way it is not place through any a lot more pain. [I cannot imagine leaving an insect on the ground helpless to be eaten alive by ants or a bird.. Even if that is Mother Nature’s way- not when I can aid it.]

So I brought him inside, I fed him insects &amp tonight he died.
He had so significantly power- you’d believe he would be fine, but he knew he couldn’t go on &amp he let go.

RIP Sad Dragonfly. ♥

Double Rainbow in Door County – Mark II

Image by elviskennedy
Elvis was meandering the backroads of Wisconsin, hunting for a excellent spot to photograph however another Door County sunset, when he turned about and was stunned to see this double rainbow. The road and the power lines ruined any vista near the roadway, so Elvis speedily grabbed his gear and headed out on foot. Rainbows are fleeting, there is no time to waste!

Then the rain started falling – in buckets. Undeterred, Elvis set up his Nikon D800 equipped with the Nikon 14-24mm lens and began firing.

Knowing how important it is to be ready (you never ever overlook some of these cub scout rules) Elvis had, just before leaving the cabin, set up the D800 to shoot 7-shot sequences, varying the shutter speed to develop photographs with exposure values of -3, -two, -1, , +1, +two and +3. The camera was also attached to the tripod and lying on the back seat – ready for action.

This allowed Elvis to focus (no pun intended) on the framing of the photographs even although he, and the camera/lens, have been receiving drenched.

In just a couple of minutes, the rainbow vanished.

Wiping down the gear and coming down from the adrenaline rush Elvis realized, as soon as once again, what a fortunate boy he is. Not only had he been fortunate adequate to be in the right place, at the correct time, he also got to knowledge life in all of its wonder.

Sight: The gorgeous and spectacular rainbow of colors in the sky, the clouds, the trees, the field and of course, the massive, bold arch overhead.

Sound: Rain splattering on the ground, on Elvis’ head and on the camera gear, punctuated by distant, rolling thunder.

Smell: The freshly reduce hay. The air, ionized by the passing storm.

Touch: The warm sun reduce by the cold raindrops. The warm breeze. The sharply reduce hay underfoot.

Taste: Even though the newly cut hay and freshness from the rain were practically adequate to taste, a large piece of tiramisu would have been amazing.

All that makes for a pot ‘o gold at the end of any rainbow. What a wonderful evening!

Patriarch R. D. Shepherd’s Homecoming 1859

1_About how a young boy from Shepherdstown
About how a young boy from Shepherdstown built a massive fortune through work, smarts and an act of his own heroism for another; then, turns around and gives much of it back as McMurran Hall, an Almshouse in New Orleans and other gifts.

2_R. D. Shepherd had a strict, flinty way
R. D. Shepherd had a strict, flinty way, but on paper and in the world at large did his huge generosities stand tall, pervade the landscape and enrich the hearts of humanity.

3_Seventy-five-year-old Rezin
Seventy-five-year-old Rezin Davis Shepherd, described by the New Orleans Picayune as having “the largest and most productive estate which has ever been held by one person in this city and State” – began the construction Thursday, October 6th, 1859 of a gift to his home town, this time right on lot no. 1 in Shepherdstown, the very lot where he was born in August 1, 1784.

4_Who knew that in ten fleeting day
Who knew that in ten fleeting days – October 16th – history would be blown off its hinges by the John Brown raiders’ attack fifteen miles away at Harpers Ferry, the match that lit the simmering fever of division between

5_North and South over slavery
North and South over slavery and claimed rights to secede from the Union. The tempest raged back and forth over the county and the town for 1300 hundred days of pitiless strife and war before settling back into being a barren, alien landscape.

6_RD’s building
RD’s (“RD” henceforth for “Rezin Davis Shepherd”) building – beautiful as were all his buildings remains a Greek Revival style, with a two-story-portico and Corinthian flourishes. But in the 1860s, it would bear witness to all that was rent asunder and itself narrowly avoid destruction, unlike a less lucky altruistic juggernaut project of Shepherd’s in New Orleans – the palatial Almshouse. But this, RD’s Town Hall, first named, would eventually live a “long, happy life” first as the County Court, then into its present-day majesty as the signature building of Shepherd University.

Growing Up – RD Learns the Trade:

7_When he was just nine years old
8_placed him in the store and counting house
When he was just nine years old, RD’s father, Abraham, placed him in the store and counting house in Baltimore of William Taylor,

9_an ambitious importer and ship-owner
an ambitious importer and ship-owner. RD’s incredible gifts surfaced when he – just eighteen – was sent to New Orleans to assure a good return on a huge shipment of British goods his firm had purchased for New Orleans’ customers. Then his first big “killing” was with another fresh-faced, hard-driving Taylor colleague, James McDonough. Wrote the Picayune: In October, 1803, it was well known throughout the country that Louisiana had been purchased by the United States. Mr. Taylor was the only merchant who seemed to comprehend the profit from one consequence of the this great political event.

10_in becoming a state
11_all sugar imports thereafter
12_cornered 1800 of those hogsheads
The firm realized that in becoming a state, a duty of 2.5 cents would be added to the price of all sugar imports thereafter. So Shepherd and McDonough – when all the sugar produced in the state was between 2100-2200 hogsheads – cornered 1800 of those hogsheads, giving young RD “a handsome capital for a young man to start in mercantile life.” He soon created a new firm shared with Taylor, then in time through age and retirement became RD’s alone.

13_Coming into his own
Coming into his own, he married Lucy Taylor Gorham of Barnstable, Massachusetts in 1808, who was “a niece and adopted daughter” of Taylor. On August 22nd, 1809, their only child, Ellen Shepherd, was born in Louisiana. (Lucy would die in 1814).

14_the penchant of RD
It was at this juncture the penchant of RD for regular, publicity-averse benefactions took root, in the moment of his willed defiance against a direct military order to work, instead, to save one particular wounded man, left for dead in war, a man who himself would live on to become the epitome of the proverbial Good Man, albeit

On reaching the bank he met a friend, who told him his friend Touro was dead. Inquiring where he was, Shepherd was informed that he had been taken to

20_Jackson’s headquarters
an old building in the rear of Jackson’s headquarters. Forgetting his orders, Mr. Shepherd went immediately to the place and found he was not dead, but, as the surgeon said, in a dying condition. Disregarding what the surgeon said, Shepherd got a cart, put him in it, administered stimulants, and took Touro to his own house. He then procured nurses, and by the closest attention, Mr. Touro’s life was saved. Mr. Shepherd returned late in the day,

21_Commodore Patterson in a bad humor
having performed his mission, to find Commodore Patterson in a bad humor, and, speaking severely to him, the latter said: “Commodore, you can hang or shoot me, and it will be all right, but my best friend needed my assistance, and nothing on earth could have induced me to neglect him.”

RD’s businesses continued to grow exponentially and his brother, James Hervey Shepherd, was summoned from Shepherdstown to assist.

1850 – In Shepherdstown & Wild Goose Farm; the 1850 Census shows 66-year-old RD with a period worth of 0,000, living only with workmen: 26-year-old German-born master stonemason Conrad Smith and an overseer. Although one account states Touro stipulated that RD free his enslaved persons, RD is shown to having owned numerous persons, enumerated in both the 1850 and 1860 Census slave schedules.

1854, January 6th – Touro’s Will makes Rezin Davis Shepherd residuary legatee of the estate and executor; 5,000 is willed to specific recipients. A sum iof ,000 is set aside for a palatial almshouse, with the added stipulation to RD that more sums, if needed, should be used to complete this priority project.

Judah Touro made out his will January 6, 1854 a few days before his death that said:

33_my dear, old, and devoted friend, Rezin Davis Shepherd
34_I hereby appoint and institute him
As regards my other designated executor, say my dear, old, and devoted friend, Rezin Davis Shepherd, to whom, under Divine Providence, I am greatly indebted for the preservation of my life when I was wounded on the 1st of January, 1815, I hereby appoint and institute him, the said Rezin Davis Shepherd, after payment of my particular legacies, and the debts of my succession, the universal legatee of the rest and residue of my estates, movable and immovable.

35_funded remodeling of the Trinity
RD continued his projects both in New Orleans and Shepherdstown. He had already funded remodeling of the Trinity

Episcopal Church. He planned a clock and bell to its original church then after some legal squabbling – the clock – to everyone’s assent – was reassigned to be inserted in to the new government building.

The Shepherd Family is Scattered By War:

37_The war hit the family hard
The war hit the family hard. Most of the young men enlisted in Virginia units. RD had to recalibrate his business strategies. Wrote the Richmond Daily Dispatch: June 8, 1861:
The New Orleans Delta states that R. D. Shepherd, Esq., who is now at an advanced time of life, living on his beautiful farm near Shepherdstown, Virginia, has directed his agent in New Orleans to pay over to the treasurer of the Confederate States a large sum of money, including, it is said, his whole annual income from rents in that city — the largest income enjoyed by any property holder — to be applied to the defence of the rights and the support of the independence of the South.

38_spring of 1862 when Federal General Banks
In the spring of 1862 when Federal General Banks with his army entered into Jefferson County, RD took refuge in Boston with his daughter.

39_As the war progressed
As the war progressed, its maw of destruction came closer to Shepherdstown’s nearly complete building. 130,000 troops moved in the area in September, 1862 for the bloody Maryland Campaign, just across the Potomac river. Wounded from the nearby battles poured into Shepherdstown, putting the unfinished Town Hall into service as an outdoor hospital.

Wrote Mary Bedinger Mitchell:

40_The unfinished Town Hall had stood in naked ugliness
The unfinished Town Hall had stood in naked ugliness for many a long day. Somebody threw a few rough boards across the beams, placed piles of straw over them, laid down single planks to walk upon, and lo, it was a hospital at once.

There were six churches and they were all full, the barn-like place known as the Drill Room, all the private houses after their capacity, the shops and empty buildings, the school-houses – every inch of space and yet the cry was for more room.

We went about our work with pale faces and trembling hands, yet trying to appear composed for the sake of our patients, who were much excited. We could hear the incessant explosions of artillery, the shrieking whistles of the shells, and the sharper, deadlier more thrilling roll of musketry; while every now and then the echo of some charging cheer would come, borne by the wind, and as the human voice would pierce that demoniacal clangor we would catch out breath and listen, and try not to sob, and turn back to the forlorn hospitals, to the suffering at our feet and before our eyes while imagination fainted at the thought of those other scenes hidden from us beyond the Potomac.

Had Federal General George McClellan crossed the Potomac and pursued General Lee’s scattered and mauled army, as historians have much criticized him since for not doing, Shepherdstown would have likely suffered greater damage, but, as it was, shells landed in the yards of the Lees and Morgans and one or two even hit Shepherd’s new Town Hall, but were of little consequence.

Property Losses in New Orleans:

41_RD’s fine residence at 18 Bourbon Street
42_18 Bourbon Street in New Orleans
More invasive, improvised use was being made of RD’s fine residence at 18 Bourbon Street in New Orleans, causing his nephew to formally appeal to the Federal powers-that-be in early 1864. He wrote:

43_From Brig. General James Bowen
January 29, 1864
From Brig. General James Bowen
Provost Marshal General
Department of the Gulf.

Sir:
The undersigned acting as the duly authorized agent and attorney in fact of Rezin Davis Shepherd, formerly the State of Virginia, but for more than eight months past residing with his daughter Mrs. Gorham Brooks in the city of Boston and State of Massachusetts, respectfully represents: That the said Shepherd is a loyal citizen of the United States and the true and lawful owner of the Brick Dwelling No. 18 Bourbon Street between Canal and Custom House Streets in the City of New Orleans and also of all the furniture and contents thereof: that in the month of June, 1862 Col. Stafford without show of authority, placed in possession of said house and contents, a man by the name of Horton or Houghton, who has ever since occupied and now occupied and uses the same as a Boarding House, and who never has paid any rent or compensation there and continually refused to do so.

Under the circumstances, the undersigned respectfully appeals to you, General, for relief, and asks that the matter be referred to Capt. Edward Page and Thomas Tileston, or other of them for investigation and that the aforesaid premises and contents be restored to the possession of the owner without delay; Henry Shepherd Jr.

Like The Town Hall, the huge, magnificent Almshouse in New Orleans remained unfinished, to be hit by a worse fate. Shepherd was charged by Touro’s will to first put ,00 toward its construction, then be prepared to put more money into its construction- including even some of Shepherd’s own funds – as recipient of Touro’s residue.

44_occupied by detachments of the 2nd Maine Cavalry
45_The fire started
46_Baked beans fired the building
On September 1, 1865, at a time the Almshouse in New Orleans – still with an unfinished, floorless top floor – was occupied by detachments of the 2nd Maine Cavalry and Company K, First Louisiana Cavalry. A baking oven was in heavy use at one end of the building so that heat would be carried through a fissure in a ventilation system close by. The fire started in the rafters above the third floor. It was night-time with a high wind and no flooring yet laid for the third floor in that wing. Coals dripping from the fire then ignited tar on the lower walls. “Baked beans fired the building” said one from the 2nd Maine Cavalry. The building was uninsured. Just a few months later R. D. Shepherd died of typhoid fever, November 10, 1865, no longer the executor of the estate, leaving no philanthropist to help make up the loss.

Wrote the editors of the Times-Picayune in a long obituary:
In his native village he erected a splendid building, designed for a town hall, also a large academy, with beautiful grounds and a walk. He also deposited with the Mayor annually a large sum to buy fuel and provisions for the poor. He also erected the largest and most costly church in Jefferson County. Many other acts of public and private benevolence were performed by him in his quiet, furtive manner.

With war ended and when he was still healthy, RD had urged that his Town Hall become the County Court since the Charlestown courthouse was a battle-scarred ruin, especially from a shelling it took in the fall of 1863.

A Visitor Contemplates Charlestown’s Ruined Courthouse in mid-1865:

47_the court-house, where that mockery of justice was performed, was a ruin
48_Four massive white brick pillars, still standing, supported a riddled roof
A short walk up into the centre of the town took us to the scene of John Brown’s trial. It was a consolation to see that the jail had been laid in ashes, and that the court-house, where that mockery of justice was performed, was a ruin abandoned to rats and toads. Four massive white brick pillars, still standing, supported a riddled roof, through which God’s blue sky and gracious sunshine smiled. The main portion of the building had been literally torn to pieces. In the floor-less hall of justice rank weeds were growing.

49_Names of Union soldiers were scrawled along the walls
Names of Union soldiers were scrawled along the walls. No torch had been applied to the wood-work, but the work of destruction had been performed by the hands of hilarious soldier-boys ripping up floors and pulling down laths and joists to the tune of “John Brown,” the swelling melody of the song, and the accompaniment of crashing partitions, reminding the citizens, who thought to have destroyed the old hero, that his soul was marching on. It was also a consolation to know that the court-house and jail would probably never be rebuilt, the county-seat having been removed from Charlestown to Shepherdstown — “forever,” say the resolute loyal citizens of Jefferson County, who rose to vote it back again.

While RD’s nephew and agent, Henry Shepherd Jr. was in New Orleans during the war, minding the family interests, three of his brothers were at war. The eldest Rezin Davis, his older brother who had a young family

52_eldest Rezin Davis, his older brother who had a young family
since 1858, died of disease November 2, 1862 at his “river cottage” after imprisonment in the Old Capitol Prison for being an associate of Confederate spy, Redmond Burke. He left his widow, Elizabeth Boteler Stockton Shepherd, two children (Fannie and Alexandria) and a third (David) on the way. Probably first buried on his farm, Rezin Shepherd (a nephew of the patriarch) was reburied after peace came in the new Elmwood Cemetery. His site was joined by all his family as time unspooled.

53_twenty-five year-old Abraham
Henry Jr.’s next brother, twenty-five year-old Abraham, enlisted May 22nd, 1861, would move over to Co. F. of the 17th Virginia Cavalry, get wounded at the third battle of Winchester in September 19, 1864, and become a prisoner of war. But he survived the war and died many years later in 1907.

54_Henry Jr.’s younger brother, James Touro (Truro) Shepherd
Henry Jr.’s younger brother, James Touro (Truro) Shepherd, enlisted as a Private May 1st, 1861 in the 2nd Virginia Infantry. Like many, the rigors of marching under Gen. Stonewall Jackson proved an impetus to transfer out into a Cavalry regiment, and he joined Co. B of Gen. Stuart’s Horse Artillery under John Pelham, with a promotion to first lieutenant. His service record ends abruptly in the spring of 1862. The Shepherdstown Register in September, 1865 reported him having died in “Richmond City” in March, 1862. His marker dates his death as August 13, 1862, which may be the date of his re-internment into the family burial ground.

Two sons of James H. and his wife, Florence Hamtramck Shepherd were buried a few feet apart in the family burial ground on Shepherdstown’s New Street adjacent to the Episcopal rectory. Robert F. Shepherd, who joined Co. H, 2nd Va. Infantry, died May 4, 1862 of pneumonia.

Rezin Davis Shepherd was buried there too, in his own time.

He left all his fortune to his daughter, who, since 1855, had been a widow.

Wrote the Shepherdstown Register: A Large Estate – the late Rezin D. Shepherd left an estate valued at about ,500,000 all of which goes to his daughter, Mrs. Brooks of Boston. He was born in 1784 (on the lot where the court house would be built). In 1809 he went to New Orleans and engaged in the commission business until 1849 and was the executor of the estate of the late Judah Touro. Mr. Shepherd was formerly a merchant in this city, residing on High Street. He accumulated a very large property in New Orleans and was reputed to be one of the wealthiest men of that city. Upon the breaking out of the rebellion, he returned to Boston and resided for a short time with his daughter and sole heir, Mrs. Gorham Brooks, widow of a son of the late Peter C. Brooks. His estate on High Street was formerly, we believe the property of Samuel Dexter.

The Massachusetts Historical Society today displays a cannon donated by the family and acquired by RD – a smaller version of the one that so severely wounded RD’s friend, Judah Touro.

The visiting journalist Trowbridge was proven wrong – the county seat DID go back to the Charlestown Courthouse. Wrote the editors of the Charlestown-based newspaper, The Spirit of Jefferson, in 1894:

58_The Normal College building, formerly the town hall
The Normal College building, formerly the town hall, on Main Street, is a handsome structure, the gift of one of the Shepherd family, Rezin D. from which the town takes its name. You will remember that it was used as a court house since the war and the courts of Jefferson county were held there, one Judge Hall sitting on the bench. A political rape was perpetuated on Charlestown, the party in power, fitly termed radicals, thought they had a sure thing of it, built a jail and added a wing to either side of the town hall, but “the best laid schemes of mice and men gang af’t aglee.” The fellows that did all this mischief were turned down by the people and things took their normal shape and Charlestown was again the county seat.

Shepherd University began when the county seat of Jefferson County, West Virginia, was moved from Shepherdstown to Charles Town in July 1871. On February 27, 1872, the Legislature of West Virginia passed the following act: “That a branch of the State Normal School be and the same is hereby established at the building known as Shepherd College, in Shepherdstown, in the county of Jefferson.”

59_RD’s descendant, Shepherd Brooks
RD’s descendant, Shepherd Brooks, made it final when he deeded the property and building over to the School and a three-person board of trustees to maintain it.

As they say, settings reverse, the tide of life had gone out – and – came back in again.

Details, quoting from Smithsonian National Air and Space Museum | Curtiss P-40E Warhawk (Kittyhawk IA):

Whether known as the Warhawk, Tomahawk, or Kittyhawk, the Curtiss P-40 proved to be a successful, versatile fighter during the first half of World War II. The shark-mouthed Tomahawks that Gen. Claire Chennault’s "Flying Tigers" flew in China against the Japanese remain among the most popular airplanes of the war. P-40E pilot Lt. Boyd D. Wagner became the first American ace of World War II when he shot down six Japanese aircraft in the Philippines in mid-December 1941.

Curtiss-Wright built this airplane as Model 87-A3 and delivered it to Canada as a Kittyhawk I in 1941. It served until 1946 in No. 111 Squadron, Royal Canadian Air Force. U.S. Air Force personnel at Andrews Air Force Base restored it in 1975 to represent an aircraft of the 75th Fighter Squadron, 23rd Fighter Group, 14th Air Force.

Long Description:
Whether it was the Tomahawk, Warhawk, or Kittyhawk, the Curtiss P-40 was a successful and versatile fighter aircraft during the first half of World War II. The shark-mouthed Tomahawks that General Claire Chennault led against the Japanese remain among the most popular airplanes of the war. In the Phillipines, Lt. Boyd D. Wagner became the first American ace of World War II while flying a P-40E when he shot down six Japanese aircraft during mid-December 1941. P-40s were first-line Army Air Corps fighters at the start of the war but they soon gave way to more advanced designs such as the Republic P-47 Thunderbolt and the Lockheed P-38 Lightning (see NASM collection for both aircraft). The P-40 is not ranked among the best overall fighters of the war but it was a rugged, effective design available in large numbers early in the war when America and her allies urgently required them. The P-40 remained in production from 1939 to the end of 1944 and a total of 13, 737 were built.

Design engineer Dr. Donovan R. Berlin layed the foundation for the P-40 in 1935 when he designed the agile, but lightly-armed, P-36 fighter equipped with a radial, air-cooled engine. The Curtiss-Wright Corporation won a production contract for 210 P-36 airplanes in 1937-the largest Army airplane contract awarded since World War I. Worldwide, fighter aircraft designs matured rapidly during the late 1930s and it was soon obvious that the P-36 was no match for newer European designs. High altitude performance in particular became a priceless commodity. Berlin attempted to improve the P-36 by redesigning it in to accommodate a turbo-supercharged Allison V-1710-11 inline, liquid-cooled engine. The new aircraft was designated the XP-37 but proved unpopular with pilots. The turbo-supercharger was not reliable and Berlin had placed the cockpit too far back on the fuselage, restricting the view to the front of the fighter. Nonetheless, when the engine was not giving trouble, the more-streamlined XP-37 was much faster than the P-36.

Curtiss tried again in 1938. Berlin had modified another P-36 with a new Allison V-1710-19 engine. It was designated the XP-40 and first flew on October 14, 1938. The XP-40 looked promising and Curtiss offered it to Army Air Corps leaders who evaluated the airplane at Wright Field, Ohio, in 1939, along with several other fighter proposals. The P-40 won the competition, after some modifications, and Curtiss received an order for 540. At this time, the armament package consisted of two .50 caliber machine guns in the fuselage and four .30 caliber machine guns in the wings.

After production began in March 1940, France ordered 140 P-40s but the British took delivery of these airplanes when Paris surrendered. The British named the aircraft Tomahawks but found they performed poorly in high-altitude combat over northern Europe and relegated them to low-altitude operations in North Africa. The Russians bought more than 2,000 P-40s but details of their operational history remain obscure.

When the United States declared war, P-40s equipped many of the Army Air Corps’s front line fighter units. The plucky fighter eventually saw combat in almost every theater of operations being the most effective in the China-Burma-India (CBI) Theater. Of all the CBI groups that gained the most notoriety of the entire war, and remains to this day synonymous with the P-40, is the American Volunteer Group (AVG) or the Flying Tigers. The unit was organized after the Chinese gave former U. S. Army Air Corps Captain Claire Lee Chennault almost 9 million dollars in 1940 to buy aircraft and recruit pilots to fly against the Japanese. Chennault’s most important support within the Chinese government came from Madam Chiang Kai-shek, a Lt. Colonel in the Chinese Air Force and for a time, the service’s overall commander.

The money from China diverted an order placed by the British Royal Air Force for 100 Curtiss-Wright P-40B Tomahawks but buying airplanes was only one important step in creating a fighting air unit. Trained pilots were needed, and quickly, as tensions across the Pacific escalated. On April 15, 1941, President Franklin D. Roosevelt quietly signed an Executive Order permitting Chennault to recruit directly from the ranks of American military reserve pilots. Within a few months, 350 flyers joined from pursuit (fighter), bomber, and patrol squadrons. In all, about half the pilots in the Flying Tigers came from the U. S. Navy and Marine Corps while the Army Air Corps supplied one-third. Factory test pilots at Bell, Consolidated, and other companies, and commercial airline pilots, filled the remaining slots.

The Flying Tigers flew their first mission on December 20. The unit’s name was derived from the ferocious fangs and teeth painted on the nose of AVG P-40s at either side of the distinctive, large radiator air intake. The idea is said to originate from pictures in a magazine that showed Royal Air Force Tomahawks of No. 112 Squadron, operating in the western desert of North Africa, adorned with fangs and teeth painted around their air intakes. The Flying Tigers were the first real opposition the Japanese military encountered. In less than 7 months of action, AVG pilots destroyed about 115 Japanese aircraft and lost only 11 planes in air-to-air combat. The AVG disbanded on July 4, 1942, and its assets, including a few pilots, became a part of the U. S. Army Air Forces (AAF) 23rd Fighter Group in the newly activated 14th Air Force. Chennault, now a Brigadier General, assumed command of the 14th AF and by war’s end, the 23rd was one of the highest-scoring Army fighter groups.

As wartime experience in the P-40 mounted, Curtiss made many modifications. Engineers added armor plate, better self-sealing fuel tanks, and more powerful engines. They modified the cockpit to improve visibility and changed the armament package to six, wing-mounted, .50 caliber machine guns. The P-40E Kittyhawk was the first model with this gun package and it entered service in time to serve in the AVG. The last model produced in quantity was the P-40N, the lightest P-40 built in quantity, and much faster than previous models. Curtiss built a single P-40Q. It was the fastest P-40 to fly (679 kph/422 mph) but it could not match the performance of the P-47 Thunderbolt and the P-51 Mustang so Curtiss ended development of the P-40 series with this model. In addition to the AAF, many Allied nations bought and flew P-40s including England, France, China, Russia, Australia, New Zealand, Canada, South Africa, and Turkey.

The Smithsonian P-40E did not serve in the U. S. military. Curtiss-Wright built it in Buffalo, New York, as Model 87-A3 and delivered it to Canada as a Kittyhawk IA on March 11, 1941. It served in No. 111 Squadron, Royal Canadian Air Force (RCAF). When the Japanese navy moved to attack Midway, they sent a diversionary battle group to menace the Aleutian Islands. Canada moved No. 111 Squadron to Alaska to help defend the region. After the Japanese threat diminished, the unit returned to Canada and eventually transferred to England without its P-40s. The RCAF declared the NASM Kittyhawk IA surplus on July 27, 1946, and the aircraft eventually returned to the United States. It had several owners before ending up with the Explorer Scouts youth group in Meridian, Mississippi. During the early 1960s, the Smithsonian began searching for a P-40 with a documented history of service in the AVG but found none. In 1964, the Exchange Club in Meridian donated the Kittyhawk IA to the National Aeronautical Collection, in memory of Mr. Kellis Forbes, a local man devoted to Boys Club activities. A U. S. Air Force Reserve crew airlifted the fighter to Andrews Air Force Base, Maryland, on March 13, 1964. Andrews personnel restored the airplane in 1975 and painted it to represent an aircraft of the 75th Fighter Squadron, 23rd Fighter Group, 14th Air Force.

Quoting from Wikipedia | Curtiss P-40 Warhawk:

The Curtiss P-40 Warhawk was an American single-engine, single-seat, all-metal fighter and ground attack aircraft that first flew in 1938. It was used by the air forces of 28 nations, including those of most Allied powers during World War II, and remained in front line service until the end of the war. It was the third most-produced American fighter, after the P-51 and P-47; by November 1944, when production of the P-40 ceased, 13,738 had been built, all at Curtiss-Wright Corporation‘s main production facility at Buffalo, New York.

The P-40 design was a modification of the previous Curtiss P-36; this reduced development time and enabled a rapid entry into production and operational service.

Warhawk was the name the United States Army Air Corps adopted for all models, making it the official name in the United States for all P-40s. The British Commonwealth and Soviet air forces used the name Tomahawk for models equivalent to the P-40B and P-40C, and the name Kittyhawk for models equivalent to the P-40D and all later variants.

The P-40’s lack of a two-stage supercharger made it inferior to Luftwaffe fighters such as the Messerschmitt Bf 109 or the Focke-Wulf Fw 190 in high-altitude combat and it was rarely used in operations in Northwest Europe. Between 1941 and 1944, however, the P-40 played a critical role with Allied air forces in three major theaters: North Africa, the Southwest Pacific and China. It also had a significant role in the Middle East, Southeast Asia, Eastern Europe, Alaska and Italy. The P-40’s performance at high altitudes was not as critical in those theaters, where it served as an air superiority fighter, bomber escort and fighter bomber.

P-40s first saw combat with the British Commonwealth squadrons of the Desert Air Force (DAF) in the Middle East and North African campaigns, during June 1941. The Royal Air Force‘s No. 112 Squadron was among the first to operate Tomahawks, in North Africa, and the unit was the first to feature the "shark mouth" logo, copying similar markings on some Luftwaffe Messerschmitt Bf 110 twin-engine fighters. [N 1]

Although it gained a post-war reputation as a mediocre design, suitable only for close air support, more recent research including scrutiny of the records of individual Allied squadrons indicates that the P-40 performed surprisingly well as an air superiority fighter, at times suffering severe losses, but also taking a very heavy toll on enemy aircraft. The P-40 offered the additional advantage of low cost, which kept it in production as a ground-attack fighter long after it was obsolete in the air superiority role.

As of 2008, 19 P-40s were airworthy.

The first Space Shuttle orbiter, "Enterprise," is a full-scale test vehicle used for flights in the atmosphere and tests on the ground; it is not equipped for spaceflight. Although the airframe and flight control elements are like those of the Shuttles flown in space, this vehicle has no propulsion system and only simulated thermal tiles because these features were not needed for atmospheric and ground tests. "Enterprise" was rolled out at Rockwell International’s assembly facility in Palmdale, California, in 1976. In 1977, it entered service for a nine-month-long approach-and-landing test flight program. Thereafter it was used for vibration tests and fit checks at NASA centers, and it also appeared in the 1983 Paris Air Show and the 1984 World’s Fair in New Orleans. In 1985, NASA transferred "Enterprise" to the Smithsonian Institution’s National Air and Space Museum.

The Jaguar E-Sort (UK) or XK-E (US) is a British automobile manufactured by Jaguar among 1961 and 1974. Its combination of good appears, high performance, and competitive pricing established the marque as an icon of 1960s motoring. A wonderful achievement for Jaguar, more than seventy thousand E-Sorts have been sold throughout its lifespan.

In March 2008, the Jaguar E-Kind ranked very first in Day-to-day Telegraph list of the &quot100 most stunning vehicles&quot of all time.[two] In 2004, Sports Auto International magazine placed the E-Type at quantity one on their list of Best Sports Cars of the 1960s.

Overview

The E-Type was initially developed and shown to the public as a grand tourer in two-seater coupé type (FHC or Fixed Head Coupé) and as convertible (OTS or Open Two Seater). The 2+2 version with a lengthened wheelbase was released numerous years later.

On its release Enzo Ferrari referred to as it &quotThe most stunning car ever made&quot.

The model was produced in 3 distinct versions which are now normally referred to as &quotSeries 1&quot, &quotSeries two&quot and &quotSeries three&quot. A transitional series among Series 1 and Series 2 is identified unofficially as &quotSeries 1½&quot.

In addition, numerous restricted-edition variants had been developed:

• The &quot’Lightweight’ E-Type&quot which was apparently intended as a sort of adhere to-up to the D-Sort. Jaguar planned to make 18 units but eventually only a dozen had been reportedly constructed. Of these, 1 is identified to have been destroyed and two others have been converted to coupé kind. These are exceedingly rare and sought following by collectors.
• The &quotLow Drag Coupé&quot was a 1-off technical exercising which was in the end sold to a Jaguar racing driver. It is presently believed to be portion of the private collection of the current Viscount Cowdray.

E1A (1957)

Soon after their accomplishment at LeMans 24 hr by means of the 1950s Jaguars defunct racing department were provided the short to use D-Sort style construction to develop a road going sports vehicle, replacing the XK150.

It is suspected that the very first prototype (E1A) was offered the code based on: (E): The proposed production name E-Sort (1): Initial Prototype (A): Aluminium construction (Production models utilized steel bodies)

The car featured a monocoque design, Jaguar’s completely independent rear suspension and the nicely proved &quotXK&quot engine.

The auto was utilized solely for factory testings and was by no means formally released to the public. The auto was eventually scrapped by the factory

E2A (1960)

Jaguar’s second E-Sort idea was E2A which unlike E1A was constructed from a steel chassis and utilized a aluminium physique. This auto was completed as a race car as it was thought by Jaguar at the time it would supply a greater testing ground.

E2A utilised a 3 litre version of the XK engine with a Lucas fuel injection system.

Soon after retiring from the LeMans 24 hr the vehicle was shipped to America to be used for racing by Jaguar privateer Briggs Cunningham.

In 1961 the car returned to Jaguar in England to be utilised as a testing mule.

Ownership of E2A passed to Roger Woodley (Jaguars consumer competitors automobile manager) who took possession on the basis the car not be employed for racing. E2A had been scheduled to be scrapped.

Roger’s wife Penny Griffiths owned E2A till 2008 when it was offered for sale at Bonham’s Quail Auction. Sale cost was US.five million

The Series 1 was introduced, initially for export only, in March 1961. The domestic industry launch came four months later in July 1961.[7] The vehicles at this time employed the triple SU carburetted 3.eight litre 6-cylinder Jaguar XK6 engine from the XK150S. The initial 500 automobiles built had flat floors and external hood (bonnet) latches. These vehicles are uncommon and far more worthwhile. Following that, the floors had been dished to offer a lot more leg area and the twin hood latches moved to inside the vehicle. The three.eight litre engine was increased to four.2 litres in October 1964.[7]

All E-Kinds featured independent coil spring rear suspension with torsion bar front ends, and four wheel disc brakes, in-board at the rear, all were power-assisted. Jaguar was a single of the initial auto makers to equip vehicles with disc brakes as standard from the XK150 in 1958. The Series 1 can be recognised by glass covered headlights (up to 1967), modest &quotmouth&quot opening at the front, signal lights and tail-lights above bumpers and exhaust suggestions under the licence plate in the rear.

3.8 litre cars have leather-upholstered bucket seats, an aluminium-trimmed centre instrument panel and console (changed to vinyl and leather in 1963), and a Moss four-speed gearbox that lacks synchromesh for 1st gear (&quotMoss box&quot). four.two litre vehicles have far more comfy seats, improved brakes and electrical systems, and an all-synchromesh four-speed gearbox. 4.2 litre cars also have a badge on the boot proclaiming &quotJaguar 4.two Litre E-Kind&quot (three.8 vehicles have a easy &quotJaguar&quot badge). Optional extras integrated chrome spoked wheels and a detachable challenging leading for the OTS.

An original E-Sort difficult best is extremely uncommon, and discovering one particular intact with all the chrome, not to mention original paint in decent situation, is rather challenging. For those who want a hardtop and are not fussy over no matter whether or not it is an original from Jaguar, a number of third parties have recreated the hardtop to practically exact specifications. The expense ranges anywhere from double to triple the cost of a canvas/vinyl soft leading.

A two+2 version of the coupé was added in 1966. The two+two provided the alternative of an automatic transmission. The body is 9 in (229 mm) longer and the roof angles are various with a much more vertical windscreen. The roadster remained a strict two-seater.

There was a transitional series of cars constructed in 1967-68, unofficially known as &quotSeries 1½&quot, which are externally similar to Series 1 cars. Due to American pressure the new features were open headlights, diverse switches, and some de-tuning (with a downgrade of twin Zenith-Stromberg carbs from the original triple SU carbs) for US models. Some Series 1½ vehicles also have twin cooling fans and adjustable seat backs. Series 2 characteristics were gradually introduced into the Series 1, producing the unofficial Series 1½ cars, but constantly with the Series 1 body style.

Much less widely known, there was also correct at the end of Series 1 production and prior to the transitional &quotSeries 1½&quot referred to above, a very little quantity of Series 1 automobiles produced with open headlights.[eight] These are sometimes referred to as &quotSeries 1¼&quot cars.[9] Production dates on these machines vary but in correct hand drive form production has been verified as late as March 1968.[10] It is thought that the low quantity of these automobiles developed relative to the other Series make them amongst the rarest of all production E Types.

An open 3.eight litre vehicle, in fact the initial such production auto to be completed, was tested by the British magazine The Motor in 1961 and had a top speed of 149.1 mph (240. km/h) and could accelerate from -60 mph (97 km/h) in 7.1 seconds. A fuel consumption of 21.3 miles per imperial gallon (13.three L/100 km 17.7 mpg-US) was recorded. The test vehicle expense £2097 such as taxes.[11]

Open headlights without glass covers, a wrap-around rear bumper, re-positioned and larger front indicators and taillights below the bumpers, far better cooling aided by an enlarged &quotmouth&quot and twin electric fans, and uprated brakes are hallmarks of Series two cars. De-tuned in US, but nevertheless with triple SUs in the UK, the engine is simply identified visually by the change from smooth polished cam covers to a a lot more industrial ‘ribbed’ look. Late Series 1½ cars also had ribbed cam covers. The interior and dashboard have been also redesigned, with rocker switches that met U.S well being and security regulations being substituted for toggle switches. The dashboard switches also lost their symmetrical layout. New seats were fitted, which purists claim lacked the style of the originals but were surely far more comfortable. Air conditioning and energy steering have been obtainable as factory possibilities.

Production according to Graham[12] is 13,490 of all types.

A new five.3 L 12-cylinder Jaguar V12 engine was introduced, with uprated brakes and common energy steering. The short wheelbase FHC body style was discontinued and the V12 was available only as a convertible and two+2 coupé. The convertible used the longer-wheelbase two+2 floorplan. It is simply identifiable by the big cross-slatted front grille, flared wheel arches and a badge on the rear that proclaims it to be a V12. There have been also a quite restricted number of four.two litre six-cylinder Series three E-Varieties built. These had been featured in the initial sales literature. It is believed these are the rarest of all E-Kinds of any remaining.

In 2008 a British classic vehicle enthusiast assembled what is surely the last ever E-Variety from components bought from the end-of-production surplus in 1974.[15]

Graham[12] lists production at 15,290.

Restricted edtions

Two restricted production E-Kind variants had been made as test beds, the Low Drag Coupe and Lightweight E-Type, both of which had been raced:

Low Drag Coupé (1962)

Shortly soon after the introduction of the E-Type, Jaguar management wanted to investigate the possibility of developing a vehicle a lot more in the spirit of the D-Sort racer from which components of the E-Type’s styling and style have been derived. One particular vehicle was constructed to test the concept made as a coupé as its monocoque design and style could only be produced rigid adequate for racing by using the &quotstressed skin&quot principle. Earlier Jaguar racers have been built as open-top cars due to the fact they have been based on ladder frame styles with independent chassis and bodies. Unlike the steel production E-Kinds the LDC utilized lightweight aluminium. Sayer retained the original tub with lighter outer panels riveted and glued to it. The front steel sub frame remained intact, the windshield was given a far more pronounced slope and the rear hatch welded shut. Rear brake cooling ducts appeared next to the rear windows,and the interior trim was discarded, with only insulation around the transmission tunnel. With the exception of the windscreen, all cockpit glass was plexi. A tuned version of Jaguar’s three.8 litre engine with a wide angle cylinder-head style tested on the D-Type racers was used. Air management became a main difficulty and, despite the fact that significantly sexier searching and definitely more rapidly than a production E-Variety, the auto was by no means competitive: the quicker it went, the a lot more it wanted to do what its design dictated: take off.

The one particular and only test bed auto was completed in summer time of 1962 but was sold a year later to Jaguar racing driver Dick Protheroe who raced it extensively and ultimately sold it. Given that then it has passed through the hands of a number of collectors on each sides of the Atlantic and now is believed to reside in the private collection of the existing Viscount Cowdray.

Lightweight E-Variety (1963-1964)

In some approaches, this was an evolution of the Low Drag Coupé. It made substantial use of aluminium alloy in the body panels and other elements. Nonetheless, with at least one particular exception, it remained an open-leading vehicle in the spirit of the D-Kind to which this automobile is a far more direct successor than the production E-Sort which is far more of a GT than a sports vehicle. The automobiles utilized a tuned version of the production 3.8 litre Jaguar engine with 300 bhp (224 kW) output rather than the 265 bhp (198 kW) developed by the &quotordinary&quot version. At least one particular automobile is recognized to have been fitted with fuel-injection.

The vehicles were entered in numerous races but, in contrast to the C-Kind and D-Sort racing cars, they did not win at Le Mans or Sebring.

Motor Sport

Bob Jane won the 1963 Australian GT Championship at the wheel of an E-Variety.

The Jaguar E-Type was extremely profitable in SCCA Production sports vehicle racing with Group44 and Bob Tullius taking the B-Production championship with a Series-three V12 racer in 1975. A couple of years later, Gran-Turismo Jaguar from Cleveland Ohio campaigned a 4.2 L 6 cylinder FHC racer in SCCA production series and in 1980, won the National Championship in the SCCA C-Production Class defeating a completely funded factory Nissan Z-automobile group with Paul Newman.

Particulars, quoting from Smithsonian National Air and Space Museum | Lockheed SR-71 Blackbird:

No reconnaissance aircraft in history has operated globally in much more hostile airspace or with such comprehensive impunity than the SR-71, the world’s fastest jet-propelled aircraft. The Blackbird’s efficiency and operational achievements placed it at the pinnacle of aviation technologies developments during the Cold War.

This Blackbird accrued about 2,800 hours of flight time during 24 years of active service with the U.S. Air Force. On its final flight, March six, 1990, Lt. Col. Ed Yielding and Lt. Col. Joseph Vida set a speed record by flying from Los Angeles to Washington, D.C., in 1 hour, 4 minutes, and 20 seconds, averaging 3,418 kilometers (two,124 miles) per hour. At the flight’s conclusion, they landed at Washington-Dulles International Airport and turned the airplane more than to the Smithsonian.

Long Description:
No reconnaissance aircraft in history has operated in much more hostile airspace or with such full impunity than the SR-71 Blackbird. It is the fastest aircraft propelled by air-breathing engines. The Blackbird’s overall performance and operational achievements placed it at the pinnacle of aviation technology developments for the duration of the Cold War. The airplane was conceived when tensions with communist Eastern Europe reached levels approaching a complete-blown crisis in the mid-1950s. U.S. military commanders desperately necessary precise assessments of Soviet worldwide military deployments, particularly close to the Iron Curtain. Lockheed Aircraft Corporation’s subsonic U-2 (see NASM collection) reconnaissance aircraft was an capable platform but the U. S. Air Force recognized that this relatively slow aircraft was currently vulnerable to Soviet interceptors. They also understood that the fast development of surface-to-air missile systems could place U-2 pilots at grave threat. The danger proved reality when a U-2 was shot down by a surface to air missile over the Soviet Union in 1960.

Lockheed’s 1st proposal for a new high speed, higher altitude, reconnaissance aircraft, to be capable of avoiding interceptors and missiles, centered on a design propelled by liquid hydrogen. This proved to be impracticable because of considerable fuel consumption. Lockheed then reconfigured the design for traditional fuels. This was feasible and the Central Intelligence Agency (CIA), already flying the Lockheed U-two, issued a production contract for an aircraft designated the A-12. Lockheed’s clandestine ‘Skunk Works’ division (headed by the gifted design engineer Clarence L. &quotKelly&quot Johnson) designed the A-12 to cruise at Mach 3.2 and fly properly above 18,288 m (60,000 feet). To meet these challenging needs, Lockheed engineers overcame several daunting technical challenges. Flying more than three times the speed of sound generates 316° C (600° F) temperatures on external aircraft surfaces, which are adequate to melt conventional aluminum airframes. The style team chose to make the jet’s external skin of titanium alloy to which shielded the internal aluminum airframe. Two standard, but very potent, afterburning turbine engines propelled this exceptional aircraft. These power plants had to operate across a huge speed envelope in flight, from a takeoff speed of 334 kph (207 mph) to far more than 3,540 kph (2,200 mph). To avoid supersonic shock waves from moving inside the engine intake causing flameouts, Johnson’s group had to design and style a complicated air intake and bypass technique for the engines.

Skunk Functions engineers also optimized the A-12 cross-section style to exhibit a low radar profile. Lockheed hoped to accomplish this by carefully shaping the airframe to reflect as tiny transmitted radar power (radio waves) as achievable, and by application of special paint created to absorb, rather than reflect, those waves. This remedy became 1 of the very first applications of stealth technologies, but it never totally met the design and style objectives.

Test pilot Lou Schalk flew the single-seat A-12 on April 24, 1962, right after he became airborne accidentally for the duration of high-speed taxi trials. The airplane showed excellent guarantee but it necessary considerable technical refinement prior to the CIA could fly the first operational sortie on Could 31, 1967 – a surveillance flight over North Vietnam. A-12s, flown by CIA pilots, operated as element of the Air Force’s 1129th Special Activities Squadron beneath the &quotOxcart&quot system. Even though Lockheed continued to refine the A-12, the U. S. Air Force ordered an interceptor version of the aircraft designated the YF-12A. The Skunk Performs, nonetheless, proposed a &quotspecific mission&quot version configured to conduct post-nuclear strike reconnaissance. This program evolved into the USAF’s familiar SR-71.

Lockheed constructed fifteen A-12s, which includes a unique two-seat trainer version. Two A-12s had been modified to carry a particular reconnaissance drone, designated D-21. The modified A-12s were redesignated M-21s. These have been designed to take off with the D-21 drone, powered by a Marquart ramjet engine mounted on a pylon in between the rudders. The M-21 then hauled the drone aloft and launched it at speeds higher enough to ignite the drone’s ramjet motor. Lockheed also constructed 3 YF-12As but this variety in no way went into production. Two of the YF-12As crashed during testing. Only one survives and is on display at the USAF Museum in Dayton, Ohio. The aft section of 1 of the &quotwritten off&quot YF-12As which was later employed along with an SR-71A static test airframe to manufacture the sole SR-71C trainer. 1 SR-71 was lent to NASA and designated YF-12C. Which includes the SR-71C and two SR-71B pilot trainers, Lockheed constructed thirty-two Blackbirds. The first SR-71 flew on December 22, 1964. Simply because of extreme operational fees, military strategists decided that the more capable USAF SR-71s should replace the CIA’s A-12s. These were retired in 1968 right after only one year of operational missions, mainly over southeast Asia. The Air Force’s 1st Strategic Reconnaissance Squadron (part of the 9th Strategic Reconnaissance Wing) took over the missions, flying the SR-71 beginning in the spring of 1968.

After the Air Force started to operate the SR-71, it acquired the official name Blackbird– for the particular black paint that covered the airplane. This paint was formulated to absorb radar signals, to radiate some of the tremendous airframe heat generated by air friction, and to camouflage the aircraft against the dark sky at high altitudes.

Experience gained from the A-12 system convinced the Air Force that flying the SR-71 safely necessary two crew members, a pilot and a Reconnaissance Systems Officer (RSO). The RSO operated with the wide array of monitoring and defensive systems installed on the airplane. This equipment integrated a sophisticated Electronic Counter Measures (ECM) method that could jam most acquisition and targeting radar. In addition to an array of advanced, high-resolution cameras, the aircraft could also carry gear developed to record the strength, frequency, and wavelength of signals emitted by communications and sensor devices such as radar. The SR-71 was created to fly deep into hostile territory, avoiding interception with its tremendous speed and high altitude. It could operate safely at a maximum speed of Mach three.3 at an altitude more than sixteen miles, or 25,908 m (85,000 ft), above the earth. The crew had to put on pressure suits equivalent to these worn by astronauts. These suits have been necessary to shield the crew in the event of sudden cabin stress loss whilst at operating altitudes.

To climb and cruise at supersonic speeds, the Blackbird’s Pratt &amp Whitney J-58 engines had been designed to operate continuously in afterburner. Whilst this would seem to dictate high fuel flows, the Blackbird in fact accomplished its greatest &quotgas mileage,&quot in terms of air nautical miles per pound of fuel burned, during the Mach 3+ cruise. A standard Blackbird reconnaissance flight may require many aerial refueling operations from an airborne tanker. Each time the SR-71 refueled, the crew had to descend to the tanker’s altitude, normally about six,000 m to 9,000 m (20,000 to 30,000 ft), and slow the airplane to subsonic speeds. As velocity decreased, so did frictional heat. This cooling impact caused the aircraft’s skin panels to shrink significantly, and those covering the fuel tanks contracted so much that fuel leaked, forming a distinctive vapor trail as the tanker topped off the Blackbird. As soon as the tanks had been filled, the jet’s crew disconnected from the tanker, relit the afterburners, and once again climbed to higher altitude.

Air Force pilots flew the SR-71 from Kadena AB, Japan, all through its operational career but other bases hosted Blackbird operations, as well. The 9th SRW sometimes deployed from Beale AFB, California, to other locations to carryout operational missions. Cuban missions were flown directly from Beale. The SR-71 did not start to operate in Europe till 1974, and then only temporarily. In 1982, when the U.S. Air Force based two aircraft at Royal Air Force Base Mildenhall to fly monitoring mission in Eastern Europe.

When the SR-71 became operational, orbiting reconnaissance satellites had currently replaced manned aircraft to collect intelligence from sites deep within Soviet territory. Satellites could not cover each geopolitical hotspot so the Blackbird remained a important tool for worldwide intelligence gathering. On many occasions, pilots and RSOs flying the SR-71 supplied information that proved vital in formulating profitable U. S. foreign policy. Blackbird crews offered critical intelligence about the 1973 Yom Kippur War, the Israeli invasion of Lebanon and its aftermath, and pre- and post-strike imagery of the 1986 raid conducted by American air forces on Libya. In 1987, Kadena-based SR-71 crews flew a number of missions more than the Persian Gulf, revealing Iranian Silkworm missile batteries that threatened industrial shipping and American escort vessels.

As the performance of space-based surveillance systems grew, along with the effectiveness of ground-primarily based air defense networks, the Air Force started to drop enthusiasm for the high-priced plan and the 9th SRW ceased SR-71 operations in January 1990. In spite of protests by military leaders, Congress revived the system in 1995. Continued wrangling more than operating budgets, even so, soon led to final termination. The National Aeronautics and Space Administration retained two SR-71As and the one SR-71B for higher-speed study projects and flew these airplanes until 1999.

On March six, 1990, the service career of one Lockheed SR-71A Blackbird ended with a record-setting flight. This unique airplane bore Air Force serial number 64-17972. Lt. Col. Ed Yeilding and his RSO, Lieutenant Colonel Joseph Vida, flew this aircraft from Los Angeles to Washington D.C. in 1 hour, four minutes, and 20 seconds, averaging a speed of 3,418 kph (two,124 mph). At the conclusion of the flight, ‘972 landed at Dulles International Airport and taxied into the custody of the Smithsonian’s National Air and Space Museum. At that time, Lt. Col. Vida had logged 1,392.7 hours of flight time in Blackbirds, far more than that of any other crewman.

This specific SR-71 was also flown by Tom Alison, a former National Air and Space Museum’s Chief of Collections Management. Flying with Detachment 1 at Kadena Air Force Base, Okinawa, Alison logged far more than a dozen ‘972 operational sorties. The aircraft spent twenty-four years in active Air Force service and accrued a total of two,801.1 hours of flight time.
