Events
Bessie Coleman attends flying school in France and became the first licensed African-American female pilot.
Mexicana de Aviación begins service.
The Imperial Japanese Navy acquires its first rigid and semi-rigid airships.
The Italian General Giulio Douhet publishes his highly influential book Command of the Air. In it, he argues that the ability of aircraft to fly over armies and navies renders those forces of secondary importance; that the vastness of the sky makes defense against bombers impossible; that only offensive bombing to destroy the enemy's air force can allow a country to achieve command of the air; that once it is achieved, a bombing campaign can be carried out against enemy "vital centers", including industry, transportation, government, communications, and "the will of the people;" and that success against enemy civilian morale in particular would be the key to victory.
January
January 6 – After modifications, HMS Argus returns to service with the Royal Navy as the world's first aircraft carrier equipped with palisades. Installed on the port and starboard edges of the flight deck and capable of being raised and lowered, the palisades when raised serve as a windbreak and prevent aircraft on the flight deck from blowing or rolling overboard in heavy weather.
