Salute!
Close, Zipper......
Plenty of aero refs on the 'net and in your local libberry.
Pprune has the Tech Log and that is where the serious stuff can be found.
PLZ stop thinking about the mach and stall correlation. Ditto for speed and gee.
You can stall a plane at close to it's max recommended or tested speed that rips the wings off or fries the motor... go see "accelerated stall", and all the basics about AoA.
Supersonic is different than subsonic and there are also wings that can handle subsonic mach numbers better than others. The phrase "sound barrier' came up was when some of our WW2 planes encountered the shockwaves at high mach....not even 0.7M in some cases, but due to the wing some air was at the mach ( I use that for 1.0, and it's an old habit). The pressure behind the shock wave changed the basic aero stability of the plane and we saw phenomena like roll reversal and aileron flutter and nose tuck and........ The T-37 trainer USAF used for a half a century had a problem above 0.6M or so, and I saw it.
So this forum may have lottsa war stories like mine and others, but you best visit the liberry on line or downtown and read a book.
Gums sends...

Reason: advice and Tech Log ref
