Couldn't agree more. Many years ago, a young teeteringhead crashed (and trashed) a military UH-1. Not my fault! Control malfunction not enemy action, so a read across to all rotary methinks.
There was a hole in the side of my helmet (probably from rotorbrake cylinder), that you could have put your fist through. That hole would have been in my head......
A few months in hospital for me; crew chief and 2 pax (without helmets) not so lucky I'm afraid.......
And I'm still flying, but
always with a helmet!!
