Back in the late '90s, I had Chuck Yeager's flight simulator program.
The SR 71 was one of the planes and it was the only one I never managed to land on the virtual runway.
I would think flying the model may be harder than flying the real thing.
I met Chuck Yeager in Cal flying a tailless canard ultralight. Like me at the time. He seemed quite leery of it. Flew it like a test pilot doing it by the numbers. That must have been about 1990.
