Joe Crane, C-1, learned parachuting in the Army from 1921 – 1924 and became a stunt man with the Burns Flying Circus after leaving the service. In 1925, when most jumpers deployed immediately out of the aircraft, Joe Crane delayed deploying his canopy for 2,250 feet to disprove the theory that a man would lose consciousness in freefall. In 1933, he organized the National Parachute Jumpers Association, a precursor to USPA. Crane died in 1968.
