Aermacchi MC-72

ammc72

 

Designed by Mario Castoldi over three years from 1931 to 1933, it was hoped this plane would enter (and win) the Schneider Trophy race of 1931 but the plane could not be ready in time for that contest (the winner was the British Supermarine S.6B).
 
First flown in June 1931, the MC.72 was a single-seat twin-float seaplane. The unique engine was effectively two in tandem driving separate (counter-rotating) propellors.
 
In late 1927, Italian Mario de Bernardi upped the world absolute speed record mark to 298 mph with a Macchi M-52 seaplane developed from the M-39 in which he had won the 1926 Schneider Race. He soon raised the mark to 318 mph with the same airplane.
 
Problems with the Fiat 24 cylinder engine hp prevented it taking part in the Schneider seaplane contests, but Francesco Agello boosted the 3 km speed record with it to 423.57 mph 10 April 1933 and then 100 km speed record to 390.8 mph. The Coupe de Vitesse Louis Bleriot record of 30 min was raised to 384.86 mph. A world speed record was established on October 23, 1934 at 440.67 mph / 709 km/h. This world speed record lasted for five years – but as a record for a piston-engine seaplane it has never been broken (likely because development of racing seaplanes essentially came to an end with the end of the Schneider Trophy contest).
 
The Schneider Trophy never experienced any casualties during competition, but several pilots were killed training for the races. Italy had five casualties: Vittorio Centurione in 1926 in a Macchi M-39; Giuseppe Motta in 1929 in a Macchi M-67; Tomasso Dal Molin in 1930 in a Savoia S.65; Giovani Monti and Stanislao Bellini in 1931 in a Macchi MC-72.
 
As a result of three consecutive victories for the British, the Schneider races were over.
