In the ultimate irony of Cold War-era surveillance, one of America’s most effective spy planes — and literally the fastest plane ever built — could never have happened without the help of its intended target, the Soviet Union.
Turns out the Americans bought the metal it needed to help the SR-71 Blackbird withstand the temperatures of supersonic travel from its longtime rival Russia. These are just a few of the fun facts the Smithsonian revealed in a recent video on the plane.
The documentary features a tour of the SR-71 at the Smithsonian National Air and Space Museum. Former Blackbird pilot Buz Carpenter joins the tour, giving the lowdown on what kept the stealthy plane up in the air. Carpenter flew the SR-71 hundreds of times during its time in service, and he even flew the airplane that now resides at the Smithsonian.The SR-71 had three nose options: A training nose, a radar nose, and a camera nose capable of taking a 72-mile wide photo. The film in that camera was 5 inches wide and 2 miles long. It had to be processed in 500-foot rolls.
The radar nose wasn’t required for navigation. The SR-71 had a pod that read the location of the stars in the sky and, as long as you gave the plane its initial position on the planet, the plane would know where it was anywhere in the world. This was 12 years before the global positioning system was first imagined by the U.S. military.
