The Heyford prototype, J9130, pictured at Radlett. It was first flown on June 12, 1930 by Maj Jim Cordes for five minutes. A second flight of ten minutes followed later the same day. The nose gunner has not just hijacked the pilot!
Access to the Rolls-Royce Kestrel engines was easy. The sides of the engine housing folded down enabling the engineers to stand while working on the engines.
Winding the elastic. The starting equipment of the Heyford was removable. On top of each wheel are supports for the shafts of the hand turning gear.
The cockpit of the prototype Heyford, J9130, photographed in May 1931. The second pilot's controls could be detached in a moment when not required, as they are in this picture. The bulkhead door dividing the pilot's cockpit from the forward gunner is open.
Close-up view of the retractable pillar box-type gun turret aft of the wings on Heyford K3489 at Radlett in June 1933.
Another view of the Heyford prototype's cockpit showing this time the copilot's controls in position and the twofold bulkhead door to the forward gunner's position closed. The large trim wheel is seen left of centre of the picture. Note too the folding seats; the higher one is in fact the backrest.
