Simply amazing. The audio is quite good. Were these the nailheads or the BBC's or do you know?
I can see why there were only a few bases that supported SR-71's around the world - not every base would have that kind of hardware. Beale AFB, RAF Mindenhall (if I recall correctly) and Kadena in Okinawa. Any others?
It sounded like engine 2 had to work a little harder to get the J-58 to light.
