Dal Molin demonstrated superior ability and temperament while serving in various Regia Aeronautica fighter squadrons, both in training and as an aerobatic pilot.

In May 1928, Dal Molin transferred to the Regia Aeronautica′s High Speed School at Desenzano del Garda, which was under the command of Lieutenant Colonel Mario Bernasconi, and began training to represent Italy in the Schneider Cup seaplane races.

[2] Dal Molin himself took part in the 1929 Schneider Cup race, held on 6 and 7 September 1929 and hosted by the United Kingdom on the air circuit at Calshot on the Isle of Man.

While conducting flight tests of the Savoia-Marchetti S.65 racing floatplane on 18 January 1930, Dal Molin was killed when the plane crashed in Lake Garda.

The poet, playwright, orator, journalist, and soldier Gabriele D'Annunzio attended a memorial service for Dal Molin, whose body subsequently was recovered by a diver.

The citation for Dal Molin's Silver Medal of Aeronautic Valor reads: A pilot of exceptional skill and admirable daring, he experimented with difficult high-speed aircraft; in an important world competition he represented the Italian air force with a result equal to the task entrusted to him.
