The Goodyear Inflatoplane was an experimental aircraft made by the Goodyear Aircraft Company , a subsidiary of Goodyear Tire and Rubber Company, well known for the Goodyear blimp. The Inflatoplane was roughly equivalent to the Piper Cub

The all-fabric inflatable aircraft was built in 1956, with the idea that it could be used by the military as a rescue plane to be dropped in a box behind enemy lines. Only 12 were built, but development continued until the project was canceled in 1973.

There were at least 2 versions:

The GA-468 was a single seater. It took about 5 minutes to inflate to about 25 lbf/in² (170 kPa); at full size it was 19 ft 7 in (5.97 m) long, with a 22 ft (6.7 m) wingspan. A pilot would then hand start the two-stroke cycle, 40 hp (30 kW) engine, and take off with a maximum load of 240 lb (109 kg). On 20 US gallons (76 L) of fuel, the aircraft could fly 390 miles (630 km), with an endurance of 6.5 hours. Maximum speed was 72 mph (116 km/h). Later, a 42 hp (31 kW) engine was used in the plane.

The GA-466 was the two seater version, 2 in (50 mm) shorter, but with a 6 ft (1.8 m) longer wingspan than the GA-468. A more powerful 60 hp (45 kW) McCulloch 4318 engine could power the 740 lb (336 kg) of plane and passenger to 70 mph (113 km/h), although the range of the plane was limited to 275 miles (440 km).
