Macchi Castoldi M.C.72
For two years, the M.C. 72 suffered from many mechanical defects, as well as the loss of two test pilots who died trying to coax world class speed out of the M.C. 72 (first Monti and then Bellini). The final design of M.C. 72 used contra-rotating propellers powered by a modified FIAT AS.6 supercharged V24 engine generating some 1,900-2,300 kW (2,500-3,100 hp).
After 35 flights, the engines were overhauled in preparation for a record attempt. The aircraft finally lived up to expectations when it set a new world speed record (over water) on 10 April 1933, with a speed of 682 km/h (424 mph). It was piloted by Warrant Officer Francesco Agellio (the last qualified test pilot). Not satisfied, development continued as the aircraft's designers thought they could break 700 km/h (430 mph) with the M.C. 72. This feat was in fact achieved on 23 October 1934, when Agello piloted the M.C. 72 for an average speed of 709 km/h (440 mph) over three passes. This record remains (as of 2012) the fastest speed ever attained by a piston-engine seaplane. After this success, the M.C.72 was never flown again.
