maybe there's a way that I have yet to try, get in altitude of 33000fl and leave the handcuffs at the most, I believe that the speed does not go beyond 310 or 320ias, the important thing and that care must be taken during the climb, a When you reach the altitude I can go where I want! 8-)
I wanted to ask you're part of some virtual AEROLINE? I am a member of the Italian Flying "italiani volanti"  ;)
