Its just like pitching a tent in your pants, only air borne. ie. Airplane, helicopter or hot air ballon.

I pitched a tent in my pants on a helicopter = I packed a parachute on the helicopter.
The girl next to me on the flight home was hot and suddenly I was Packing a Parachute.

Derived from the sacred motto of parachutists, meaning to put your condom on yourself.
Whatever you do, pack your own parachute. She's been around with a vengeance.
