A 1912 magazine article concerns machine gun inventor Isaac N. Lewis and his machine gun, the Lewis gun. The Lewis Gun played a major roll during the First World War, having been purchased in large quantities by the British/Commonwealth armies. Written just two years prior to the slaughter, this article is about U.S. Army experiments with the Lewis Gun when it is mounted on aircraft. As the article makes clear, the Lewis Gun was the first machine gun to have ever been fixed to a plane.
