Macchi M.14

The Macchi M.14 was an Italian single seat fighter that had the honour to be the first land based fighter developed by the Italian firm.
It was designed by Alessandro Tonini who designed it to be a single-seat wooden sesquiplane with Warren truss interplane bracing. It was armed with two forward firing synchronized Vickers 0.303in machine guns.
It had a fixed landing gear and was powered by a single 110hp LeRhône 9J engine.
Macchi started the testing in the spring of 1918 but the prototype was destroyed a bit later, in June 1918. However Macchi built another ten airplanes which were tested at Guidonia's test centre less than one year later, in 1919. In spite of not having being ordered and not being therefore massed produced, the ten ones served as advanced trainers and apparently one of them was sold to a private owner and flew with the registration I-BADG.
