The Boeing Model 42 (also Boeing XCO-7 for Experimental Corps Observation Model 7) was an American biplane aircraft developed from the Airco DH.4, taking advantage of the large number of aircraft left over after the end of World War I.

Development and design

The Model 42 was essentially an Airco DH-4M-1 fitted with new Boeing tailplanes, tapered wings, and tripod landing gear. The first aircraft built, designated XCO-7, was used as a static test bed, and did not fly. The second aircraft, XCO-7A, used a standard DH-4M-1 fuselage and Liberty engine, with the Boeing modifications. The final aircraft, XCO-7B, added balanced elevators and inverted the Liberty engine. Both flyable aircraft were shipped to McCook Field, where the first flight occurred on 6 February 1925. [1]

The performance of the new aircraft did not justify the cost of the conversion, and Boeing abandoned the project. [2]

Boeing GA-1

The Boeing GA-1 was an armored triplane. Designed in 1919, it was powered by a pair of modified Liberty engines driving pusher propellers. The first of the Engineering Division's heavily armored GAX series aircraft, the ponderous airplane was intended to strafe ground troops while remaining immune to attack from the ground as well as from other enemy aircraft. It was so well armored that its five-ton weight proved excessive.

Airco DH.3

The Airco DH.3 was a British bomber aircraft of the First World War. The DH.3 was designed in 1916 as a long-range day bomber by Geoffrey de Havilland, chief designer at the Aircraft Manufacturing Company. It was a large biplane with wide-span three-bay wings, slender fuselage, and a curved rudder. It was powered by two 120 hp (89 kW) Beardmore engines, mounted as pushers between the wings. In addition to tailskid landing gear, two wheels were placed beneath the nose to prevent bumping.

Boeing L-15 Scout

The Boeing L-15 Scout or YL-15 was a small, piston engine liaison aircraft built by Boeing in very small numbers after World War II. It was a short take-off and landing (STOL) aircraft powered by a 125 hp Lycoming engine. The L-15 was an attempt by Boeing to expand its product line as World War II drew to a close, and Boeing's production of combat aircraft declined. Boeing decided against marketing the L-15 as a general aviation aircraft, and the twelve that were produced went to the United States Army for testing, then were transferred to the United States Fish and Wildlife Service in Alaska for various duties.

Boeing Model 204

The Boeing Model 204 was an American biplane, pusher configuration flying-boat aircraft built by Boeing in 1929. Externally, the 204 looked identical to the Boeing Model 6E, but a number of internal changes, including increasing the passenger capacity to four, gave it a new type certificate and model number.

Boeing Model 81

The Boeing Model 81 was an American training aircraft built by Boeing in 1928. The Model 81 was a development of the Model 64. It was powered by a newly developed engine, the 125 hp Fairchild-Caminez 4-cylinder radial engine. Operating at a much lower rpm than most engines it required the use of a large high-pitch propeller.
