IF I had my way, every one of these big helos would be equipped with a huge air bag that would cushion the fall if the power fails and the helo heads earthward. We lose too many good man to these helo crashes.

A really big 'chute would probably work better, maybe complemented by a smaller airbag.

Of course the Chinook, and other twin rotor helicopters, such as the CH-46 Sea Knight, can have midair collisions with themselves.

Yeah, the rotors pass through the same airspace, and if the synchronization is off then the pilots are going to need more than a clean pair of underwear.
