Osprey Rappel

Rappelling is a technique  of vertically traversing a distance by using rope.  Below, a Marine departs an Osprey using this technique.

I learned to rappel in the '70s when I was playing with the Air Cavalry.  I've never departed an Osprey, but I have departed from Huey's using this technique.  It's a very cool way to get out of an aircraft when for some reason, the aircraft can't actually land.
