The man who would become 'Airborne' graduated U.S. Army Airborne School, and was known for his aloofness in the ranks and his over-zealousness in the helicopters. He failed a psychiatric exam after an unfortunate 'accident' where a fellow infantry trooper left the chopper sans parachute. Without enough evidence for a court-martial, he was medically discharged. Less than happy with his dismissal and pension, he hooked up with another former jumper -- Crazy Legs -- and a new, better-paying profession. They were eventually noticed and picked up as muscle for the G.I. Joe organization. Airborne is currently losing favor with Top Joe Brass for the inability to ask prisoners follow-up questions due to the high rate of defenestration* around him. Airborne spends his free time watching David Letterman. His favorite segment is the 'dropping things from the roof' segment. His steel-toe boots and arm guards aren't just ornamental -- they also help crack plate glass windows...

*defenestration
n. An act of throwing someone or something out of a window.
