| - The Lockheed SR-71 Type A Aka Blackbird Is a strategic reconnaissance aircraft (hence the "SR": Strategic Reconnaissance) long-range developed by Lockheed from the projects YF-12 and A-12.
- The Lockheed SR-71 "Blackbird" is a long-range, Mach 3+ strategic reconnaissance aircraft that was operated by the United States Air Force. It was developed as a black project from the Lockheed A-12 reconnaissance aircraft in the 1960s by Lockheed and its Skunk Works division. American aerospace engineer Clarence "Kelly" Johnson was responsible for many of the design's innovative concepts. During aerial reconnaissance missions, the SR-71 operated at high speeds and altitudes to allow it to outrace threats. If a surface-to-air missile launch was detected, the standard evasive action was simply to accelerate and outfly the missile. The SR-71 was designed with a reduced radar cross-section.
- Life support was needed since the SR-71 cruises at about 80,000 feet which is very high. The plane tended to leak fuel while it was standing on the ground. It was due to cooling down fule tank seals. If you put a human in that altitude they would die about 5-15 seconds later because of a loss of oxygen. To counter this, pilots would wear a pressure suit for oxygen and anti-pressure. The suit was also used for touching the keyboards because the plane gets very hot when it is at mach 3.2 (due to air friction.) The pressure suit was a good suit for SR-71 pilots, and soon in the early 1980s people started using it on the Space Shuttle. It's last flight was in 1999, and has since been on display in museums.
