Don't try this at home. The pilot was nearly killed chasing me down the cliff in that Huey and once I got in the door he found at that altitude he couldn't back away as fast as the helicopter was falling what with the grade increasing, eventually hit the side but by this time everybody was out the door anyway from the spin. The brave woman that tried to strap me in had to unstrap herself and she fell too. Other Answers (7) Yes, special forces are often inserted using the MH-6 "Little Bird".

So long as the helicopter doesn't make strong sudden movements, the instantaneous and continuous gravitation forces to the air crew and passengers is negligible. because in stabilised turn, the ONLY force acting against your body
