    Lockheed SR-71 / YF-12 Blackbird

    Just wondering if anyone knows what the tested maximum altitude and speed of the A-12/SR71 was? I contacted the USAF recently and they simply stuck to the published figures saying it flew at 85,000ft and could reach Mach 3.3. This doesn't seem to make sense as variants of the F-4, F-104 and...
