Development

The S-36 was a modified and larger version of the earlier S-34 and was designed as a commercial aircraft for six passengers or freight. It was an amphibian sesquiplane with a boat hull fuselage and retractable landing gear. It was powered by two Wright Whirlwind J-5 engines and had a crew of two and room for six passengers on two facing bench seats. Only six aircraft were built.

Operational history

One aircraft named Dawn was sold to Mrs Frances Grayson for an attempt to be the first woman to fly across the Atlantic. As a passenger in Dawn and after two false starts the aircraft departed for the Atlantic attempt on 23 December 1927 but was not seen again.^[1]

The United States Navy bought one aircraft, designated the XPS-1, for evaluation as a patrol aircraft, it was fitted with a gunner's position in the bow although it was used as a transport.^[1]

The fourth aircraft was delivered to Pan American Airways in December 1927.^[1]
