I liked the "Top Gun" one aswell, made me laugh.
As a helicopter jocky it can really make you cringe what they do to us:
1/ Engines winding down on decent
2/ Engines winding up upon lift off
3/ Yes every helicopter IS a Bell 47!
4/ when shot, at going completely out of control and 'spinning' down to die with bags of smoke in the cabin and both hands a foot plus the badie fighting the cyclic!
I think it was in "Earthquake" where the two chaps are flying a Gazelle with the throttle off and the rotor brake on
And my piece of resistance: 'Behind Enemy Lines' where three Bell 212's took off and turned into one Bell 412 and two Bell 205's upon reaching the target and back again when landing back on the carrier!.... I know, I was flying one of the 205's!!!
