[1] Benoist used "Model XII" to several aircraft that shared the same basic engine and wing design, but differed in fuselage and control surfaces.

The first example named the "Military Plane" had a small box frame covered fuselage that left the occupants mostly exposed to the wind.

On 1 March 1912, Albert Berry used a headless Type XII to complete the first parachute jump from an airplane.

On 6 November 1912 Tony Jannus flew a model XII mounted with floats 1,973 mi down the Missouri and Mississippi rivers from Omaha, Nebraska to New Orleans arriving on 16 December.

[5] A Model XII, factory No.32 built by Edward and Milton Korn in Benoist's shop is on display at the Smithsonian's Steven F. Udvar-Hazy Center.
