[quote=pdf27;389279]Ummm... you'll have to forgive me being a little sceptical on that one. If something can do 0.95 Mach at 20,000ft there is no fundamental aerodynamic reason it isn't supersonic under the right conditions. Controllability is a minor issue, but one that I'd be stunned if they didn't fix during the flight test programme.

I have the manuals here. Who said anything about M0.95 at 20,000'?

Where did this figure come from?

I think it is just one of those 'facts' bandied about that originated in: a) Mis-information, b) dis-information, c) a typographical error, d) a 'slip of the tongue', e) a guess, f) a boast or g) anything else!

What glider were you referring to?
