parachute jump   (パラシュートジャンプ)

Four professional parachutists performed the parachute jump from the rear exit stair of the Boeing 727.

In August 1956, the recon platoon made its first parachute jump from a jet aircraft, the F3D-2 Skyknight.

After a free-fall with the RAF in 1973, Noakes held the record for the longest free-fall parachute jump by a British civilian for a time.
