Short answers, pulled from the story.
The Regia Aeronautica was established as an independent Italian air force on the 28th of March 1923, separating from the Royal Italian Army. It remained independent until 1946, when Italy became a republic and the force was renamed the Aeronautica Militare.
Francesco Agello set a floatplane world speed record of 709 km/h (440.6 mph) in the Macchi-Castoldi MC-72 in October 1934. That record for piston-engined seaplanes has never been broken.
General of Aviation Italo Balbo organized and led the 1933 Decennial Air Cruise, a formation flight of Savoia-Marchetti S.55 flying boats covering 19,000 km round trip. The route included stops in Amsterdam, Reykjavik, Montreal, Chicago, and Washington D.C., with a famous landing on Lake Michigan in front of Chicago Navy Pier.
The Corpo Aereo Italiano, the Italian air corps sent to support the Luftwaffe, flew from Nazi-occupied Belgium from October 1940 to April 1941. It lost 36 aircraft and 43 aircrew without achieving a single confirmed aerial victory, with the RAF reporting zero losses in the two aerial clashes that took place.
Teresio Vittorio Martinoli and Franco Lucchini each recorded 22 kills, the highest individual totals in surviving pilot log books. Leonardo Ferrulli followed with 21 kills, and Franco Bordoni-Bisleri and Luigi Gorrini each claimed 19. The Regia Aeronautica did not officially track individual scores; kills were reported at the unit level.
After the armistice on the 8th of September 1943, the Regia Aeronautica split into two separate forces. The Royalist Italian Co-belligerent Air Force flew for the Allies, while the National Republican Air Force flew for the Italian Social Republic and the Axis. The two Italian air forces never fought each other directly.
