Although it seemed an improbable project, the finished aircraft proved to be capable of meeting its design objectives, although orders were never forthcoming from the military.

[1] The inflatable surface of this aircraft was actually a sandwich of two rubber-type materials connected by a mesh of nylon threads, forming an I-beam.

When the nylon was exposed to air, it absorbed and repelled water as it stiffened,[clarification needed] giving the aircraft its shape and rigidity.

A pilot would then hand-start the two-stroke cycle,[1] 40 horsepower (30 kW) Nelson engine, and takeoff with a maximum load of 240 pounds (110 kg).

The test program at Goodyear's facilities near Wingfoot Lake, Akron, Ohio showed that the inflation could be accomplished with as little as 8 psi (544 mbar), less than a car tire.

[1] The flight test program had a fatal crash when Army aviator Lt. "Pug" Wallace was killed.

[8] A sixth is on display in the US Army Aviation Museum's Training Support Facility in Fort Novosel, Alabama.
