In 1911 the French army wanted to have an aircraft easily transportable and quickly dismountable from one location to another by road or railway. It was also required that the aircraft could be reassembled quickly. Baron Edmond de Marçay and Emile Moonen simplified the problem by imagining a device with wings folding along the fuselage, which was triangular and completely covered. The pilot could fold the wings without help and afterwards, according to the inventors, drive the machine on the road like a car, using the steerable rear wheels. The machine was first presented at the 1911 exhibition.
