This is a list of aviation-related events from 1940:

Events

January

February

March

  • The United States begins construction of a U.S. Navy seaplane base at Midway Atoll.
  • March 2 – The United Kingdom and France promise to send 100 bombers with crews and bombs to assist Finland at once, but do not follow through on the promise.
  • March 6 – France informs the Finnish government that it will dispatch an expeditionary force including 72 bombers to Finland on March 13, but the Winter War ends before the French force can begin its journey.
  • March 13 – The Winter War between the Soviet Union and Finland ends in the defeat of Finland. During the 3-month war, the Finnish Air Force has grown from 96 to 287 aircraft, and has lost 62 aircraft in air-to-air combat and 59 more damaged beyond repair, while the Soviet Union has lost between 700 and 900 – 725 confirmed destroyed and about 200 unconfirmed – of the 2,500 to 3,000 aircraft it has committed to the campaign, and another 300 damaged. The Soviet Air Force has dropped 150,000 bombs – about 7,500 tons (6,803 tonnes/metric tons) of bombs – on Finnish territory, but has performed poorly; its operations in early December 1939 had failed to disrupt Finnish mobilization and, despite unusually clear weather in January and February, it failed to disrupt the lone railroad connecting Finland with the outside world for more than a few hours at a time or to disrupt Finnish merchant shipping, despite 60 air raids on Finnish ports.
