I was in the Navy and just watched the Hueys fly overhead with feet,legs hanging out.
My cousin was a medic on Hueys during Vietnam.He said they were strapped in to the bench seat, then closed the doors.
My other cousin was infantry and said they just sat on the deck, or on the edge and never fell out.
A fellow worker said he fell out at low altitude on a turn,losing his M-16 and helmet in the bush.
Watching Inside Combat Rescue, the medics seem not to be belted or harnessed in the chopper.
They close the doors as they carry wounded.
How do they not fall out in a turn or in case the helo has to do an evasive action?
Are they hooked somehow to the chopper?
