Caterpillar Club

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 saving their life by parachute and ownership of the aircraft are not factors in determining qualification for membership; anybody who has saved their life 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 club was founded by Leslie Irvin of the Irvin Airchute Company of Canada in 1922. (Though Leslie Irvin is credited with inventing the first free-fall parachute in 1919, parachutes stored in canisters had saved the lives of observers in balloons and several German, Austro-Hungarian pilots of disabled military aircraft in the First World War.) The name "Caterpillar Club" simply makes reference to the silk threads that made the original parachutes thus recognising the debt owed to the silk worm. Other people have taken the metaphor further by comparing the act of baling out with that of the caterpillar letting itself down to earth by a silken thread. Another metaphor is that caterpillars have to climb out of their cocoons to escape.

"Life depends on a silken thread" is the club’s motto.

An early brochure of the Irvin Parachute Company credits William O'Connor 24 August 1920 at McCook Field near Dayton, Ohio as the first person to be saved by an Irvin parachute, but this feat was unrecognised. On 20 October 1922, Lieutenant Harold R. Harris, chief of the McCook Field Flying Station, jumped from a disabled Loening W-2A monoplane fighter. Shortly after, two reporters from the Dayton Herald, realising that there would be more jumps in future, suggested that a club should be formed. Harris became the first member and from that time forward any person who jumped from a disabled aircraft with a parachute became a member of the Caterpillar Club. Other famous members include General James Doolittle, Charles Lindbergh and (retired) astronaut John Glenn.
