The Swallow Model C Coupé is an American-built general-purpose high-wing monoplane of the mid 1930s.[3][4][5] E. B. Christopher, Swallow Aircraft Company president and designer of the Model C, was killed in the crash of an early example that he was flying.[6]

Design and development

The Model C is a high-wing, strut-braced monoplane of conventional configuration with an enclosed cabin and fixed tailwheel undercarriage.[3] Seating is provided for the pilot and one passenger, side-by-side, and the cabin is equipped with dual controls.[3] Power is supplied by a Menasco C-4 air-cooled inverted inline engine, driving a two-bladed propeller.[3]

The fuselage and tail is built from welded steel tube, covered in fabric.[3] The wing is of mixed wood and metal construction, also covered in fabric.[3] Long V-struts braced the wings to the lower longeron of the fuselage.[3]

Operational history

The Model C first flew in January 1936.[2] In April 1937, Swallow company president E. B. Christopher, who had designed the aircraft, exhibited an example at an air show in Los Angeles.[6] On April 9, he departed with it, heading to San Francisco with a single passenger aboard, investment broker E. A. Grumm.[6] Grumm was reportedly interested in arranging finance for Swallow to manufacture the Model C.[6] According to witnesses, the aircraft was struggling against a headwind as it attempted to navigate Tejon Pass at less than 100 ft (30 m) altitude.[6] A sudden downdraft blew the aircraft into a ridge, wrecking it and killing both men instantly.[6]

Following the tragedy, Swallow's new president, Sam Bloomfied, still intended marketing the Model C as late as September 1937.[7]
