A17-716 being used to test the storpedoette, a small version World War 2 storpedo. An Australian invention, the storpedo used a small parachute to slow the descent of a canister designed to absorb shocks. It was cheaper than a conventional parachute but offering more protection than dropping with no chute at all. The storpedoette was for smaller aircraft than the storpedo required, in particular to deliver critical medical supplies accurately. A17-716 was sold in civil buyers in 1955.
