Model Name:  Mayo Vought  Simplex BiPlane

The Mayo Radiator Works, a subsidiary of the Simplex Automobile Co., was  pushing for Simplex to enter the aircraft production industry. Vought signed on as engineer and designed the Mayo  Type A reconnaissance tractor biplane. By August 1915, it had completed 200 successful flights. Quickly detachable  fittings allowed the airplane to be taken from a crate and assembled in 28 minutes and dismantled in 20 minutes.

The only Mayo A Simplex built was eventually purchased by England for use as a trainer. Unfortunately, no orders  were forthcoming from either the British or American governments and the project was dropped.
