The Blackbird appears to be the first interstellar space-ship to enter service with the US air force. One of the worlds most distinctive aircraft for its completely unique shape and menacing black/black-red paint scheme, the SR-71A is the fastest "conventional" aircraft ever built (With the SR-71A, the word conventional must be applied liberally). Along with the U-2, the Blackbird has been the most successful reconnaissance aircraft produced by Lockheed's concentrated Skunk Works. However, the ability to outperform a MiG-25 did not come without a serious amount of development and testing. Each SR-71A mission is physically exhausting for its crews, who require the same credentials as an astronaut to fly this jet. All systems have to be reinforced and stress-tested to prepare them for Mach-3 flight. And with its looks and a maximum service ceiling so high it's practically in orbit, there is no surprise that it gets similar treatment to the space shuttle.
