The Lockheed SR-71 Blackbird is an American long range, high altitude strategic reconnaissance aircraft that entered United States Air Force service in 1966, capable of sustained flight at over three times the speed of sound. Built substantially from titanium to withstand the heat of high speed flight, it remains among the fastest air breathing crewed aircraft ever flown.
