Master of Acrobatic Flight

[Yossarian]

Heads up for if your trying to get the 'Master of Acrobatic Flight' achievement on the 360.

I just spent ages doing outside loops and spins but never got the on screen card telling me I had performed it, but when I did the last manoeuvre (Split S) the achievement unlocked any way. So if your getting frustrated trying to pull off those two moves the game does register that you have done them even though it does not tell you it has.
