Design and development

The HD 34 was a twin-engine biplane designed for long-range reconnaissance. The center section had a front cockpit with side-by-side seating, with the third crewmember in the rear cockpit.^[1][2]

On June 26, 1928, the HD.34 suffered damage on a test flight after losing control. It was decided, however, not to repair the aircraft due to high costs of repair.
