The Caterpillar Club is an informal association of people who have successfully used a parachute to bail out of a disabled aircraft. After authentication by the parachute maker, applicants receive a membership certificate and a distinctive lapel pin. The nationality of the person whose life was saved by parachute and ownership of the aircraft are not factors in determining qualification for membership; anybody whose life was saved by using a parachute after bailing out of a disabled aircraft is eligible. The requirement that the aircraft is disabled naturally excludes parachuting enthusiasts in the normal course of a recreational jump, or those involved in military training jumps.
The Airborne Systems company of New Jersey continues the tradition of certifying members and awarding pins to this day.[1]
