Details, quoting from Smithsonian National Air and Space Museum: Steven F. Udvar-Hazy | Northrop P-61C Black Widow:

The P-61 Black Widow was the first U.S. aircraft designed to locate and destroy enemy aircraft at night and in bad weather, a feat made possible by the use of on-board radar. The prototype first flew in 1942. P-61 combat operations began just after D-Day, June 6, 1944, when Black Widows flew deep into German airspace, bombing and strafing trains and road traffic. Operations in the Pacific began at about the same time. By the end of World War II, Black Widows had seen combat in every theater and had destroyed 127 enemy aircraft and 18 German V-1 buzz bombs.

The Museum’s Black Widow, a P-61C-1-NO, was delivered to the Army Air Forces in July 1945. It participated in cold-weather tests, high-altitude drop tests, and in the National Thunderstorm Project, for which the top turret was removed to make room for thunderstorm monitoring equipment.

Long Description:
The P-61 Black Widow was the first United States aircraft designed from the start to find and destroy other aircraft at night and in bad weather. It served in combat for only the final year of World War II but flew in the European, Mediterranean, Pacific, and China-Burma-India theaters. Black Widow crews destroyed 127 enemy aircraft and 18 robot V-1 buzz bombs.

Jack Northrop’s big fighter was born during the dark days of the Battle of Britain and the London Blitz in 1940. British successes against German daylight bombers forced the Luftwaffe (German Air Force) to shift to night bombing. By the time Royal Air Force (RAF) Spitfires could launch, climb out, and then try to intercept these raids, the bombers crews had usually dropped their loads and turned for home. An aircraft was needed to patrol the skies over England for up to seven hours during the night, and then follow radar vectors to attack German aircraft before they reached their target. U.S. Army Air Corps officers noted this requirement and decided that America must have a night fighter if and when it entered the war.

The Army awarded a contract to Northrop on January 30, 1941. The resulting design featured twin tail booms and rudders for stability when the aircraft closed in behind an intruder. It was a large aircraft with a big fuel load and two powerful engines. Armament evolved into four 20 mm cannons mounted in the belly firing forward and a powered, remote-controlled turret on top of the center fuselage equipped with four .50 cal. machine guns. The three-man crew consisted of the pilot, a gunner seated behind him, and a radar observer/gunner at the rear behind the gun turret. Only the pilot could fire the cannons but any of the three could operate the machine guns.

Simultaneously, work was proceeding, at a laboratory run by the Massachusetts Institute of Technology, to develop the airborne radar set. The Army tested an early design in a Douglas B-18 in 1941. The much-improved SCR-520 set was ready by early 1942. Meanwhile, Army enthusiasm for the XP-61 produced another contract on March 10, 1941, for 13 service-test YP-61s. Even before these airplanes flew, Northrop received orders for 410 production machines! Northrop test pilot Vance Breeze flew the aircraft on May 26, 1942. Although the Black Widow was nearly as large as a medium bomber, it was a true fighter. The only prohibited flight maneuvers were outside loops, sustained inverted flight, and deliberate spins.

As Northrop advanced the design toward production, supply problems arose and modifications became necessary. The 4-gun top turret was the same type fitted to the top forward position on the Boeing B-29 Superfortress (see NASM collection) and that bomber had production priority over the P-61. As a result, several hundred P-61s did not have this turret. Those that did experienced buffeting when the turret was traversed from side to side and a fix took time. By October 1943, the first P-61s were coming off the line. Training started immediately, and the first night fighters arrived in the European Theater by March 1944. Combat operations began just after D-Day (June 6) and the Black Widows quickly departed from their original role as defensive interceptors and became aggressors. They flew deep into German airspace, bombing and strafing trains and road traffic and making travel difficult for the enemy by day and at night.

P-61s arrived in the Pacific Theater at about the same time as the European Black Widows. For years, the Japanese had operated lone bombers over Allied targets at night and now U. S. fighters could locate and attack them. However, on June 30, 1944, a Mitsubishi BETTY (see NASM collection) became the first P-61 kill in the Pacific. Soon, Black Widows controlled the night skies. On the night of August 14-15, a P-61 named "Lady in the Dark" by her crew encountered an intruding Nakajima Ki-43 Hayabusa (Peregrine Falcon) OSCAR (see NASM collection) and eventually forced it into the sea without firing a shot. Although the war was officially over, no one was sure that all of the Japanese had heard the message and stopped fighting. The American night fighters flew again the next night and "Lady in the Dark" again found a target. It was a Nakajima Ki-44 Shoki (Demon) TOJO and the fighters maneuvered wildly as they attempted to gain an advantage. The P-61 crew lost and reacquired the Ki-44 several times then finally lost it for good and returned to base. The next day ground troops found the wrecked TOJO. In the darkness, Lady in the Dark’s crew had forced the Japanese pilot to fly into the ground, again without firing a shot.

With the war over, the Army cancelled further production. Northrop had built 706 aircraft including 36 with a highly modified center fuselage. These F-15As (later redesignated RF-61C) mounted a number of cameras in the nose and proved able reconnaissance platforms. Many of these airplanes participated in the first good aerial photographic survey of the Pacific islands. A few, plus some special purpose P-61s, stayed in active service until 1950.

NASM’s Black Widow is a P-61C-1-NO, U.S. Army Air Forces serial number 43-8330. Northrop delivered it to the Army on July 28, 1945. By October 18, this P-61 was flying at Ladd Field, Alaska, in cold weather tests and it remained there until March 30, 1946. This airplane later moved to Pinecastle Air Force Base, Florida, for participation in the National Thunderstorm Project. The project’s goal was to learn more about thunderstorms and to use this knowledge to better protect civil and military airplanes that operated near them. The U. S. Weather Bureau and the National Advisory Committee for Aeronautics (NACA) undertook the study with cooperation from the Army Air Forces and Navy. With its radar and particular flight characteristics, the P-61 was capable of finding the most turbulent regions of a storm, penetrating them, and returning crew and instruments intact for detailed study.

Pinecastle personnel removed the guns and turret from 43-8330 in July 1946 to make room for new equipment. In September, the aircraft moved to Clinton County Army Air Base, Ohio, where it remained until January 1948. The Air Force then assigned the aircraft to the Flight Test Division at Wright-Patterson Air Force Base, Ohio. After declaring the airplane surplus in 1950, the Air Force stored it at Park Ridge, Illinois, on October 3 along with important aircraft destined for the National Air Museum.

But 43-8830 was not done flying. NACA asked the Smithsonian to lend them the aircraft for use in another special program. The committee wanted to investigate how aerodynamic shapes behaved when dropped from high altitude. The Black Widow arrived at the Ames Aeronautical Laboratory, Naval Air Station Moffett Field, California, on February 14, 1951. NACA returned the aircraft and delivered it to the Smithsonian at Andrews Air Force Base, Maryland, on August 10, 1954. When the engines shut down for the last time, this P-61 had accumulated only 530 total flight hours. Smithsonian personnel trucked it to the Paul Garber Facility in Suitland, Maryland. In 2006, the aircraft was preserved and assembled at the Udvar-Hazy Center. The three different paint schemes from its past service life have been revealed by carefully removing individual layers of paint.

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.

Quoting Smithsonian National Air and Space Museum | Vought F4U-1D Corsair :

By V-J Day, September 2, 1945, Corsair pilots had amassed an 11:1 kill ratio against enemy aircraft. The aircraft’s distinctive inverted gull-wing design allowed ground clearance for the huge, three-bladed Hamilton Standard Hydromatic propeller, which spanned more than 4 meters (13 feet). The Pratt and Whitney R-2800 radial engine and Hydromatic propeller was the largest and one of the most powerful engine-propeller combinations ever flown on a fighter aircraft.

Charles Lindbergh flew bombing missions in a Corsair with Marine Air Group 31 against Japanese strongholds in the Pacific in 1944. This airplane is painted in the colors and markings of the Corsair Sun Setter, a Marine close-support fighter assigned to the USS Essex in July 1944.

Staff Sgt. Salvatore A. Giunta

Staff Sgt. Salvatore A. Giunta

U.S. Army photo

President Barack Obama presented the Medal of Honor for conspicuous gallantry to Staff Sgt. Salvatore Giunta, U.S. Army, in a ceremony held in the East Room of the White House Nov. 16, 2010 — the first living service member from the Iraq or Afghanistan wars to receive it.

When enemy forces in Afghanistan’s Korengal Valley ambushed then-Spc. Giunta’s platoon on the evening of Oct. 25, 2007, the infantry team leader braved heavy enemy fire to rescue fellow paratroopers.

(To veiw the 30-minute U.S. Army Africa video interveiw with Staff Sgt. Giunta, go to: Vicenza paratrooper to be awarded Medal of Honor from US Army Africa on Vimeo.

Giunta, of Company B, 2nd Battalion, 503rd Infantry Regiment, 173rd Airborne Brigade Combat Team, will be awarded the Medal of Honor, the U.S. military’s highest award for valor under fire.

The Hiawatha, Iowa-native is the first living service member to earn the award since Vietnam. The medal will be presented in a ceremony at a date and time still to be determined.

A 2003 graduate of Cedar Rapids Kennedy High School, Giunta has served two tours of Afghanistan. Now a staff sergeant serving in Vicenza, Italy, Giunta of Hiawatha, Iowa, knew of the nomination several months ago, but the announcement still came as a shock.

“This is a great honor, but it is not mine to take sole ownership of. I only did the next thing that needed to be done, and I was only able to do that because all of the men around me had the rest taken care of. It’s hard to take credit for simply taking the next step when so many steps had already been taken by everyone else,” Giunta said.

Not a day goes by that Giunta, now a staff sergeant serving at Vicenza’s Caserma Ederle, does not recall what he and fellow paratroopers faced that evening.

The first platoon of Company B – known to 173rd paratroopers as “Battle Company” – were heading back to their base camp in Afghanistan’s Korengal Valley following a long day watching over fellow paratroopers in an Afghan village. It was the final day of Operation Rock Avalanche. Throughout the day, enemy radio intercepts spoke of an impending attack.

Evening was approaching as Giunta’s platoon stretched in to a snaking file down the spur to the Korengal outpost. Roughly thirty paces separated each paratrooper as the moved out.

Sgt. Joshua Brennan, a 22-year-old team leader from Ontario, Ore., on his second tour in Afghanistan, was up front. Behind Brennan, manning an M249 squad automatic weapon, was Spc. Frank Eckrode then squad leader, Staff Sgt. Erick Gallardo, 24, Chula Vista, Calif.

AH-64 Apache helicopters chopped the moonlit evening above as the platoon made their way down goat trails.

Giunta, who carried an M-4 assault rifle was just behind with his team. Pfc. Kaleb Casey carried his M249 squad automatic weapon, followed by Pfc. Garrett Clary with an M203, a 5.56 mm rifle combined with a 40 millimeter grenade launcher.

Along their path, more than a dozen enemy fighters waited, readying their Russian-style rocket propelled grenades, PKM 7.62 mm heavy machine guns, and Kalishnikov rifles. They had set up an L-shape, with an RPG and PKM at the apex of the formation. As Brennan walked just 30 feet from their over watch position, the enemy open fired.

An enemy RPG exploded, followed by a burst of machine gun fire. Brennan fell to the ground. China Machine guns fired at the platoon’s flank. Eckrode was hit. He dropped to the ground, returned fire and tried to find cover.

Gallardo tried to run forward, but was met with RPG explosions and sustained machine gun fire. He returned fire and started back to Giunta’s position, falling into a ditch as an AK-47 round struck his helmet. Giunta jumped up, exposing himself to deadly fire, to assist his squad leader.

Giunta ran just a few steps when two enemy AK-47 rounds struck his body. The first shot hit the body armor on Giunta’s chest, the second hit over his left shoulder, striking a disposable rocket launcher strapped to his rucksack. But Giunta kept going, reaching Gallardo and dragging him back to where Giunta’s fire team had begun fighting back.

Gallardo got Giunta’s team online and the four paratroopers began bounding through withering enemy fire to rescue Eckrode and Brennan. Dropping for cover, they prepared fragmentation grenades to throw at the enemy to cover their next move. Casey continued to fire his machine gun at enemy muzzle flashes, less than a half city block away. Gallardo counted to three and the team hurled grenades toward enemy positions. Once they heard the explosions, they moved closer to their wounded comrades.

Eckrode called out. He was wounded, but still trying to fight. Gallardo started first aid on Eckrode while Casey, who found a bullet hole in his uniform, scanned for enemy targets.

Giunta and Clary kept running toward where Brennan fell, only to find two enemy fighters carrying a severely-wounded Brennan away. While still running, Giunta fired his assault rifle, causing them to drop Brennan and flee. Giunta emptied the rest of his magazine, killing one enemy. Giunta knelt down to help Brennan as Clary ran past, firing 40-milimeter rounds toward the retreating enemy.

Giunta saw Brennan’s injuries were severe and required more than he could offer there on the battlefield. He removed Brennan’s gear and began treating his buddy, while calling back to Gallardo for help. Brennan was trying to talk. Giunta reassured his friend as he tended to Brennan’s wounds.

Other paratroopers from the platoon were also wounded. Spc. Hugo Mendoza, was killed. Brennan, who was hoisted into a helicopter, later succumbed to his wounds.

“Giunta is a great friend and an outstanding paratrooper,” said Gallardo, now serving with Battle Company in Afghanistan. “His actions that day meant the difference between life and death to myself and other Soldiers. For that I am grateful.”

“To infinity and beyond” – This quote of Toy Story always comes in my mind when I create photos like this. By using exposure times longer than 15 seconds you always get some special effects which you cannot see with you eyes.
Maybe that’s why a lot of my photos use the technique.

Thanks for all the nice words to my Times Square shot. I try to bring out more shots this month. Always connected to the time I find on working with the whole photography thing. If you like spread the word about the shots or reblog it somewhere.

I created a Tumblr account. If you have one add me, you’ll find me under sprengben.tumblr.com/

So far I wish a great next week in your Jobs, Schools, Universities, and also to those who have holidays! 🙂 Cheers to you!

Quoting Smithsonian National Air and Space Museum | Naval Aircraft Factory N3N:

In 1934 the Naval Aircraft Factory in Philadelphia was tasked to manufacture a new primary trainer for the U.S. Navy. Following successful tests, this little biplane trainer was built in both land and seaplane versions. The Navy initially ordered 179 N3N-1 models, and the factory began producing more than 800 N3N-3 models in 1938. U.S. Navy primary flight training schools used N3Ns extensively throughout World War II. A few of the seaplane version were retained for primary training at the U.S. Naval Academy. In 1961 they became the last biplanes retired from U.S. military service.

This N3N-3 was transferred from Cherry Point to Annapolis in 1946, where it served as a seaplane trainer. It was restored and displayed at the Naval Academy Museum before being transferred here.

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

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.

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

No reconnaissance aircraft in history has operated globally in more hostile airspace or with such complete impunity than the SR-71, the world’s fastest jet-propelled aircraft. The Blackbird’s performance and operational achievements placed it at the pinnacle of aviation technology 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 last flight, March 6, 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 (2,124 miles) per hour. At the flight’s conclusion, they landed at Washington-Dulles International Airport and turned the airplane over to the Smithsonian.

Long Description:
No reconnaissance aircraft in history has operated in more hostile airspace or with such complete impunity than the SR-71 Blackbird. It is the fastest aircraft propelled by air-breathing engines. The Blackbird’s performance and operational achievements placed it at the pinnacle of aviation technology developments during the Cold War. The airplane was conceived when tensions with communist Eastern Europe reached levels approaching a full-blown crisis in the mid-1950s. U.S. military commanders desperately needed accurate assessments of Soviet worldwide military deployments, particularly near the Iron Curtain. Lockheed Aircraft Corporation’s subsonic U-2 (see NASM collection) reconnaissance aircraft was an able platform but the U. S. Air Force recognized that this relatively slow aircraft was already vulnerable to Soviet interceptors. They also understood that the rapid development of surface-to-air missile systems could put U-2 pilots at grave risk. 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 first proposal for a new high speed, high 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 conventional fuels. This was feasible and the Central Intelligence Agency (CIA), already flying the Lockheed U-2, 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. "Kelly" Johnson) designed the A-12 to cruise at Mach 3.2 and fly well above 18,288 m (60,000 feet). To meet these challenging requirements, Lockheed engineers overcame many daunting technical challenges. Flying more than three times the speed of sound generates 316° C (600° F) temperatures on external aircraft surfaces, which are enough to melt conventional aluminum airframes. The design team chose to make the jet’s external skin of titanium alloy to which shielded the internal aluminum airframe. Two conventional, but very powerful, afterburning turbine engines propelled this remarkable aircraft. These power plants had to operate across a huge speed envelope in flight, from a takeoff speed of 334 kph (207 mph) to more than 3,540 kph (2,200 mph). To prevent supersonic shock waves from moving inside the engine intake causing flameouts, Johnson’s team had to design a complex air intake and bypass system for the engines.

Skunk Works engineers also optimized the A-12 cross-section design to exhibit a low radar profile. Lockheed hoped to achieve this by carefully shaping the airframe to reflect as little transmitted radar energy (radio waves) as possible, and by application of special paint designed to absorb, rather than reflect, those waves. This treatment became one of the first applications of stealth technology, but it never completely met the design goals.

Test pilot Lou Schalk flew the single-seat A-12 on April 24, 1962, after he became airborne accidentally during high-speed taxi trials. The airplane showed great promise but it needed considerable technical refinement before the CIA could fly the first operational sortie on May 31, 1967 – a surveillance flight over North Vietnam. A-12s, flown by CIA pilots, operated as part of the Air Force’s 1129th Special Activities Squadron under the "Oxcart" program. While 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 Works, however, proposed a "specific mission" version configured to conduct post-nuclear strike reconnaissance. This system evolved into the USAF’s familiar SR-71.

Lockheed built fifteen A-12s, including a special two-seat trainer version. Two A-12s were modified to carry a special reconnaissance drone, designated D-21. The modified A-12s were redesignated M-21s. These were designed to take off with the D-21 drone, powered by a Marquart ramjet engine mounted on a pylon between the rudders. The M-21 then hauled the drone aloft and launched it at speeds high enough to ignite the drone’s ramjet motor. Lockheed also built three YF-12As but this type never 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 one of the "written off" YF-12As which was later used along with an SR-71A static test airframe to manufacture the sole SR-71C trainer. One SR-71 was lent to NASA and designated YF-12C. Including the SR-71C and two SR-71B pilot trainers, Lockheed constructed thirty-two Blackbirds. The first SR-71 flew on December 22, 1964. Because of extreme operational costs, military strategists decided that the more capable USAF SR-71s should replace the CIA’s A-12s. These were retired in 1968 after only one year of operational missions, mostly 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 began to operate the SR-71, it acquired the official name Blackbird– for the special 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 program convinced the Air Force that flying the SR-71 safely required 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 included a sophisticated Electronic Counter Measures (ECM) system that could jam most acquisition and targeting radar. In addition to an array of advanced, high-resolution cameras, the aircraft could also carry equipment designed to record the strength, frequency, and wavelength of signals emitted by communications and sensor devices such as radar. The SR-71 was designed 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 3.3 at an altitude more than sixteen miles, or 25,908 m (85,000 ft), above the earth. The crew had to wear pressure suits similar to those worn by astronauts. These suits were required to protect the crew in the event of sudden cabin pressure loss while at operating altitudes.

To climb and cruise at supersonic speeds, the Blackbird’s Pratt & Whitney J-58 engines were designed to operate continuously in afterburner. While this would appear to dictate high fuel flows, the Blackbird actually achieved its best "gas mileage," in terms of air nautical miles per pound of fuel burned, during the Mach 3+ cruise. A typical Blackbird reconnaissance flight might require several aerial refueling operations from an airborne tanker. Each time the SR-71 refueled, the crew had to descend to the tanker’s altitude, usually about 6,000 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 effect caused the aircraft’s skin panels to shrink considerably, 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 were filled, the jet’s crew disconnected from the tanker, relit the afterburners, and again climbed to high altitude.

Air Force pilots flew the SR-71 from Kadena AB, Japan, throughout its operational career but other bases hosted Blackbird operations, too. The 9th SRW occasionally deployed from Beale AFB, California, to other locations to carryout operational missions. Cuban missions were flown directly from Beale. The SR-71 did not begin to operate in Europe until 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 already replaced manned aircraft to gather intelligence from sites deep within Soviet territory. Satellites could not cover every geopolitical hotspot so the Blackbird remained a vital tool for global intelligence gathering. On many occasions, pilots and RSOs flying the SR-71 provided information that proved vital in formulating successful U. S. foreign policy. Blackbird crews provided important 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 over the Persian Gulf, revealing Iranian Silkworm missile batteries that threatened commercial shipping and American escort vessels.

As the performance of space-based surveillance systems grew, along with the effectiveness of ground-based air defense networks, the Air Force started to lose enthusiasm for the expensive program and the 9th SRW ceased SR-71 operations in January 1990. Despite protests by military leaders, Congress revived the program in 1995. Continued wrangling over operating budgets, however, soon led to final termination. The National Aeronautics and Space Administration retained two SR-71As and the one SR-71B for high-speed research projects and flew these airplanes until 1999.

On March 6, 1990, the service career of one Lockheed SR-71A Blackbird ended with a record-setting flight. This special 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, 4 minutes, and 20 seconds, averaging a speed of 3,418 kph (2,124 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, more than that of any other crewman.

This particular 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 more than a dozen ‘972 operational sorties. The aircraft spent twenty-four years in active Air Force service and accrued a total of 2,801.1 hours of flight time.

85mm 1.8 on 5D Mark ii, f/22, 1/160, ISO 320. I had been shooting everything at the machine shop with my 35mm 1.4 for a while, but I’m starting to like the longer lens for shots like this now.

Strobist info:

LP160 at full power into 45" shoot-through umbrella opposite the camera and slightly to the left.

LP160 at full power into 60" reflective umbrella behind and above me (and slightly to the right).

50" white pop-up reflector opposite the camera and to the right of the shoot-through umbrella. This almost forms half of a light tent along with the umbrella.

Triggered by a pair of Pocket Wizard Plus ii tranceivers and the optical slave function on the other LP160.

I’m thinking about getting a 100mm macro lens for shots like this. I am pretty much at the minimum focusing distance of the 85mm 1.8 here. Or I might get a 12mm extension tube. I think the 85 worked pretty well here, but these are big parts (I think it’s a 2ftx2ft pallet). I would like to be able to shoot products that are smaller than this in a similar style, so I’m trying to figure out if I should get a macro lens and/or the 12mm tube.

Be sure to post any comments/questions/suggestions that you have on the lighting, or anything else…
