In the mid 1920s Goodyear constructed a number of small scale airships designed to demonstrate and train pilots in lighter-than-air craft, the Pilgrim was one of these. It was made of a magnesium coated steel tube frame with a rubberized fabric balloon. The envelope had a capacity of 55,000 cubic feet of gas and was the first airship designed to utilize helium as the lifting gas.
The engine was a single Lawrence air-cooled three cylinder engine of 40 hp, with a 40 gallon fuel tank, giving it had a range of 525 miles. Launched in 1925, it made 4765 flights before being retired in 1931.
