The Merćep 1912 aka Merćep-Rusjan Military-Monoplane of 1912 or Rusjan-Novak No.2, was the second design after the crash of the Slovenian aviation pioneer Eduardo Rusjan. Earlier, Eduardo Rusjan had moved with his brother to Zagreb, Croatia, where Guiseppe Rusjan and Dragutin Karlo Novak then continued to build aircraft for the “Agramer Aëroplanfabrik M. Merćep”, set up by the businessman Mihajlo Merćep in Zagreb.

Mellander Monoplane 1911

This machine was built at the Sint-Job-in-‘t-Goor airfield, Belgium, in the hangars of baron Pierre de Caters, by the Swedish inventor Janne Mellander, who lived in Antwerp at the time. In 1911 he was granted French patent No. 422954, which disclosed some details of his rather fragile-looking machine, which was equipped with an automatic stabilization device and had the wings mounted very high on a secondary fuselage.
Melfa VCA-1

The VCA-1 is a tiny single-seat, low-wing monoplane of all-metal construction. The wing section is NASA GA(W)-1 with no sweepback.

Melbourne Aircraft Corp MA-2 Mamba

The MAC Mamba, Mamba Range is an Australian two-seat light aircraft designed and built by the Melbourne Aircraft Corporation.
The Mamba is a strut-braced, high-wing monoplane designed over two years and first flown on 25 January 1989. It has fixed tricycle landing gear and is powered by a 116 hp (87 kW) Lycoming O-235 flat-four piston engine. It has an enclosed glazed cabin with side-by-side configuration seating for two. The fuselage is constructed of welded steel tubing with stressed aluminum skin. It was intended to introduce four-seat and military versions of the Mamba.
The military version was built under contract by Australian Aircraft Industries as the AA-2S Mamba powered by an IO-360.

Meckler-Allen New York hydro-biplane

The Meckler-Allen airplane was built by Allen Canton and John J. Meckler in 1912 for an attempt to make a transatlantic flight. At the time it was the largest airplane in the world, measuring 104 ft long, and 76 ft across. It had a long triangular fuselage, an auxiliary wing between the main biplane cell and the biplane tail, twenty-two tanks of gasoline, five engines and miles of rigging wires. It was constructed out in the open, at a place called Clason Point in the South Bronx of New York City, on the waterfront of the East River opposite LaGuardia Airport.
