"Lieutenant W.C.Cambray MC demonstrates the technique needed to protect this FE2d of 20 Squadron in 1917. The pilot has a forward-firing Lewis gun, as does Cambray.

"To protect his tail he had to stand and use this pole-mounted weapon. In a pitching, rolling dog-fight his feet are just below the rim of the cockpit and he has no seat belt.

Note the camera on the left of the nacelle and the bomb racks underneath. The object on the top of the wing - and in danger of being shot off - is the gravity-feed fuel tank." - Aces High: The Air War Over The Western Front 1914-18 by Alan Clark
