Parachuting with AM radio back then? It would be scary to hit the ground with a heavy AM rig on yer back but wasn't that what was done?
I thought I heard him say that it was a BC-610E model. Can you imagine jumping out of an airplane with a 610 strapped to your back?
It would be much easier to do today with a class E rig. You could use a wind mill generator for power part of the way until you opened your parachute and then switch over to the newly invented solar panel parachute
This would be the green way to do it!
