While it is fascinating, I don’t think it would work in this game. For one thing, all your facts that shows the top speed of all these aircraft, in fact, the top speed of the SR-71, YF-12A, etc are still classified, as well as the max altitude.
Secondly, the aircraft would be too fast for the maps used in WT.
I have seen this plane at the National Air Force Museum in Dayton, OH. I love it and the SR-71.
BTW, the A-12 was not called a Blackbird. It was called Archangel.
