Another solution was to mount the machine gun on the top wing, where it could fire over the propeller. This made aiming difficult, and reloading was troublesome (the Lewis machine gun on the top wing only held 47 rounds of ammunition) but it was an effective solution. Here, Kiffin Rockwell stands in front of a Nieuport 16 with a machine gun on the top wing. Note the extra ammunition drums in a rack on the side of the plane. This plane happens to be one most often used by fellow Lafayette Escadrille pilot Elliot Cowdin, as evidenced by the insignia on the side. (Photo courtesy of Washington & Lee University)
