I read an unpublished interview of Bill Park (second pilot to fly the A-12) in which he didn't say the fastest or highest flights. He regarded the question as irrelevant. He said it was hard enough to get the aircraft to fly at the specified speed and altitude, do a 180° turn, and come back, so that Lockheed would have met the terms of the contract and could get paid.JimK said:FighterJock said:So what was faster in terms of overall speed? A-12 or SR-71A? I have heard many stories over the years that the SR-71A was faster than the A-12, could someone clear this up for me. :-\

I would interpret the equality of Mach numbers listed as a propulsion system limitation.
Thanks for that JimK, good information that has gone on to help me with my initial problem. B)
The aircraft went through a patch of exceptionally cold air, which is a boon to attaining higher speed. It accelerated to (based on what I was told) Mach 3.47 and perhaps an altitude of greater than 93,000 feet. (It may have been as much as 95 or 96K, but the person who was telling me this couldn't remember exactly.)
