One of the coolest things I have ever done was to skydive out of a 727 jet. They brought an Amerijet cargo version to the World Freefall Convention in Quincy Illinois back in "95. After installing seatbelts and getting signed off by the FAA you could jump it for $59, a deal in my book. 185mph exit right down the air stair, just like DB Cooper. There were at least a dozen guys dressed like DB making the jump. Other jumps that week for me included a Super Constellation, hot air balloon, Bell Jet Ranger Helicopter, PT17 Stearman Bipe and a Martin 404. I miss those days.
