SEE ALSO DB-2,

In Aug 1939 the DB-1 prototype was modified to test the feasibility of firing a large-caliber cannon from aircraft. A forward-firing 75mm was mounted in a fixed position in the bomb bay and the nose was cut down to accommodate the muzzle for initial tests over Lake Erie and at Aberdeen Proving Grounds. Vibration during firing proved excessive, and the experiments were discontinued. However, data gathered were of value in developing the cannon-firing versions of North American B-25G/H.

Douglas Cloudster Douglas #1 (Aerofiles)

Douglas Cloudster Modified (Roy Nagl coll)

Cloudster (Davis-Douglas) 1921 = 1pOB; 400hp Liberty 12; span: 55'11" length: 36'9" v: 120 range: 550 ceiling: 19,160'; ff: 2/24/21 (p: Eric Springer). The first airplane to lift its own weight in payload. Douglas' first commercial venture, designed to fly across the country, an endeavor that ended in Texas after an engine failure. POP: 1; sold in 1925 to Ryan Air Lines, where the fuselage was modified to hold 10 passengers and the plane proved quite successful in the role of an airliner, but when the business failed it went into charter work. In 1926, on a charter to Ensenada, Mexico, in a beach landing the pilot hit the surf and the damaged plane was abandoned to the incoming tide. Davis, principal financier of the new company, later gained fame in his own right as designer of the renowned Davis airfoil.
