A Cooper vane (also sometimes called a Dan Cooper switch or D.B. Cooper device) is a mechanical aerodynamic wedge that prevents the ventral airstair of an aircraft from being lowered in flight.[1] In the United States, following three hijackings in 1972, the Federal Aviation Administration ordered that Boeing 727 aircraft be fitted with Cooper vanes.[2] The device was named for an unidentified airplane hijacker dubbed D. B. Cooper, who used the rear stairway to exit a Boeing 727 in flight and make his escape via parachute.

Anyone know if the C-9 was ever used for paradrops? It seems like it would have come in handy for that at some point, but I can’t find any references to it actually being used that way.

Didn’t they use that in Airforce One when they all parachuted out?

That was a 747 that they took some artistic liberties with, so YMMV.
