Undoubtabley one of the fastest winged aircraft ever built, the Lockheed SR-71 Blackbird was far and away way ahead of it's time.
The "Blackbird" was flown by the US Air Force, CIA and NASA as a high speed reconnaissance and high altitude test platform. If you've never seen one in flight, here's your chance.
