Truly a remarkable machine...even more so for the time it was produced and operated.
I'm not yet ready to believe that little story about asking ATC for groundspeed readouts, as I don't know that the SR-71 was equipped with VHF radios, but most of the other information seems pretty accurate, if very basic.
I am envious of your experience, rokadaous. I'll have to settle for my time spent admiring the aircraft at a museum in Kansas.
How far are you into your flight training, wharthog3?
