[1] He emigrated to the United States on the RMS Oceanic from Cherbourg, France, on July 20, 1914, subsequently residing in Great Neck, New York.

[2] Bossi married Flora Kehrer, a Swiss German from Lausanne who had been sent away by a new stepmother to the United States immediately prior to the outbreak of World War I and was living with her aunt and uncle in Connecticut.

The Wright brothers' Flyer, having successfully flown in December 1903, impressed Bossi so much that he devoted himself to aviation, becoming the second licensed pilot in Italy.

[1][page needed] [3] In early December 1909, the first flight of an Italian-designed and built aircraft was successfully completed alongside fellow engineers Giuseppe M. Bellanca and Paolo Invernizzi.

During this decade, Bossi also worked for the Aviation Corps, assisting the Italian government with building and organizing its naval air forces.

Due to the economic and social difficulties in Italy following the war, in 1918, Bossi emigrated to the United States, where he eventually became a naturalized citizen.

[6][7][8][9] In 1927, Bossi was a co-founder of the company Société Continentale Parker in France together with Robert Deté, Louis Paulhan and Pierre Prier.

In October 1928, Bossi founded the American Aeronautical Corporation (AAC), officially located at 730 Fifth Avenue in Port Washington, New York, to build Savoia-Marchetti seaplanes under license.

[11] The S-56 became the first plane used by the New York City Police Department, which used it to enforce flying regulations, assist with sea rescues, and to chase rum-runners during the Prohibition era.

In 1930, the company made its first foray into the aviation industry by signing contracts to manufacture aircraft wheels and stainless steel wing ribs.

Built under Restricted License NR749,[14] its design utilized concepts developed for the Savoia-Marchetti S-31 and was powered by a single 210 horsepower (160 kW) Kinner C-5 motor.

The test rider achieved a speed of 23 miles (37 km) per hour, but one drawback was noted: the gyroscopic effect of the propeller generated so much torque that the bicycle became unstable.

Bossi concluded, erroneously, that a successful human-powered aircraft would therefore require two counter-rotating propellers to cancel out the effects of torque – similar to the design of a helicopter.

Due to the newly formed Rome-Berlin axis, similar political and military events were staged during the initial period in both Italy and Germany to help strengthen that bond.

[3] On March 18, 1937, at Cinisello airport near Milan, the plane was launched at a height of 29.5 feet (9.0 m) and Casco successfully pedaled the craft for its full 0.62 miles (1.00 km).

[21] This set a world record for human-powered flight, but as a catapult launch was not permitted in the rules of the competition, the Pedaliante did not win the prize for which it was designed.

A two-bladed vertical tail rotor was included in its design to counter the effects of torque and the landing gear was configured in a fixed tricycle form.
