Well I ended up watching the second part of the documentary today on youtube and it appears the case will go unsolved. Cooper seemed like a pretty smart guy. I can't understand why he appeared to be so unprepared for dealing with hypothermia once he hit the ground. Jumping in a thin suit and loafers doesn't make a lot of sense. Maybe if he had some sort of survivalist training he felt assured of making a fire but it was late November and raining so I would have to assume that even if he survived the jump itself that he would have been in the early stages of hypothermia when he hit the ground.
