Military Aircraft HM-1
The Military Aircraft HM-1, derived from the earlier Hawks Miller HM-1 racing aircraft nicknamed, "Time Flies" was an American prototype attack/observation aircraft. The HM-1 did not achieve production after the sole example was destroyed during testing.
==Design and development==
In 1936, Hawks had approached Howell W. "Pete" Miller, chief engineer for the Granville Brothers and responsible for their famous Gee Bee racers, to create a racing aircraft from his own design, the Hawks Miller HM-1. With an advanced aircraft design that still relied heavily on wood construction, the HM-1 featured innovative design elements, including the unusual feature of "burying" the cockpit with a curved windshield contoured to fit the fuselage top, creating a very streamlined shape. The cockpit was extended for takeoff and landing, but retracted in flight, with the pilot's seat lowered and the windshield becoming flush with the fuselage.
After its first flight on October 18, 1936, Hawks flew "Time Flies", from Hartford, Connecticut to Miami, Florida on April 13, 1937, in 4 hours and 55 minutes.〔 He then flew to Newark Airport, New Jersey, in 4 hours and 21 minutes, but bounced on landing at Newark, and broke a wooden spar in the right wing with other spars also damaged.〔Kinert 1969, pp. 84–85.〕
Short of funds, Hawks decided not to rebuild the aircraft and sold the rights to the design, including engineering data to Tri-American Aviation, a concern that wanted to convert the design into a fast two-seat attack/observation aircraft.〔Boyne 1978, p. 12.〕 The aircraft was redesigned to include two machine guns in the wings and another machine gun mounted in a flexible mount in the new rear cockpit.
