Jacob Earl "Jake" Fickel (January 31, 1883 – August 7, 1956) was a general officer and an instructor of aviation in the United States Army. He served as a private, corporal and sergeant, prior to being commissioned an officer and rising to the rank of major general. He served in the Philippines, California, and Washington, D.C., and is credited with firing the first recorded gunshot from an airplane, showing that a plane would not break up due to the gun's recoil. His concept of shooting guns from an airplane led to an airplane machine gun system that was first used in World War I.
