By 1914 most aircraft were of tractor configuration, with the engine and propeller in front of the pilot, and attempting to fire a machine gun through the propeller arc was likely to end in said pilot having a very bad day.At first designers simply worked around the problem, building pusher-style aircraft with the propeller in the rear and the gunner in the front, such as the Vickers F.B.
