I would like to help you with some suggestions on how to find D.B. Cooper. You probably have thought of the same things that I'm about to mention or they may have been suggested? But if not here they are. Why not a similar drop from a 727 with conditions the same accept, leave the darkness out. Have at least ten Sky divers leave at 30 sec intervals along the suspected departure
