was looking around the web, and came up on this.
--- Quote ---No one walks out of a 727 under 100 kts unless they are on the ground. I have over 6000 hrs. in all 3 seats of a 727 and have a FAA Check Airman Rating as a Captain and Flight Engineer. The 727 has pneumatic, electrically actuated outflow valves that close at 11,000 ft. in a decompression and the passenger oxygen masks deploy at 14,000 ft. It has an excellent manual control of the outflow valves as a back-up. There is absolutely no pressurization control issue with a bullet penetration in a 727 and I can attest that it will take considerable punishment in the air or on the ground.

Read the info on Coopers action. They were under 10,000 feet with the gear down and the airspeed was 100 knots and he was having them fly in that manner. They had been flying that way with the tail steps closed since they left the airport where he got the money and the chutes. Two military jets were shadowing them and a NG Trainer joined in the surveillance. Altitude and airspeed are pretty well documented. They didn't know that he was going out till the rear stairs opened and lowered which the pilot knew by the warning indicator. That's all in the published info off the report. He walked off the steps to freefall although he was never seen. It's a fact that he left the plane. Some of the money was recovered on the ground years later. Going off the rear of the 727 is probably the only way it could have been done. A side door exit at that speed would no doubt cause the jumper to hit the side of the plane and maybe the tail just due to the speed. Combat aircraft even in HALO jumps don't move that fast. Anyway, it doesn't matter, it was only of interest due to the Glasers development reason's.
