Isn't there some sort of ELT transmitter they could put on the harness for situations like his?
@Smokin Joe Yes,and I would be shocked to discover he wasn't wearing one. Then again,as the loadmaster on a USAF aircraft,there is no one there to monitor him and order him to put one on,and chances are he had operated around open ramps thousands of times and never fallen out before,so may not have seen the need to wear one. It's usually the pros that make the rookie mistakes because the rookies are too scared to take chances.
There is also a more remote possibility he was wearing one and it was damaged somehow.
It's not going to do him any good,but I strongly suspect there is an AF officer somewhere in that chain of command that has been ripped a new one over this loss even though he wasn't there. In the military you are responsible for the injuries or deaths of the people under your command even if you are a thousand miles away.
