Armorer's School at Wilbur Wright Field in Fairfield, Ohio during World War One. An experimental setup was created to simulate the propeller of an airplane using a motorcycle engine installed on a frame and a synchronized mechanism. Two machine guns were fired, and the shots were recorded on a rotating disc, demonstrating the potential impact on a propeller. In the photo, one of the machine gun muzzles can be seen.
