President Franklin D. Roosevelt asks the United States Congress to strengthen the air power of the United States, which he describes as "utterly inadequate."^[3]
During flight testing, the prototype of the Imperial Japanese Army Air Force′s (IJAAF) Nakajima Ki-43 (Allied reporting name "Oscar") fighter displays poor takeoff and landing characteristics and proves to be far less maneuverable and only slightly faster than the fighter it is intended to replace, the Nakajima Ki-27 (Allied reporting name "Nate"). The IJAAF considers ending further development of the Ki-43, but its co-designer, Hideo Itokawa, convinces the IJAAF to allow him to redesign the aircraft.^[4]

Three people on board die, but the commercial tanker Esso Baytown rescues the 10 survivors after they spend 10 hours in the water.
January 26 – In the Spanish Civil War, Barcelona surrenders to Nationalist forces. In the days leading up to the surrender, Nationalist aircraft have raided the city continually, especially targeting ships in port to prevent them from saving Republican refugees from capture.^[8]
January 29 – Karl Bode breaks the world altitude record for helicopters, flying a Focke-Wulf Fw 61 helicopter to an altitude of 3,427 meters (11,243 feet). It is the last official record set by a German helicopter produced prior to 1945.

February

February 4 – The Boeing XB-15 prototype, assigned to the United States Army Air Corps 2nd Bombardment Group at Langley Field, Virginia, takes off^[9] under the command of Major Caleb V. Haynes to carry 3,250 pounds (1,470 kg) of American Red Cross emergency supplies to Santiago, Chile, in the wake of the 1939 Chillán earthquake. It arrives at Santiago only 30 hours later, making only two stops along the way, at France Field in the Panama Canal Zone, and at Lima, Peru. Haynes will receive the Distinguished Flying Cross and the Order of the Merit of Chile for the flight, and the XB-15's entire crew will receive the 1939 MacKay Trophy for it.

It loses power and crashes during its final approach at Mitchell Field, but its pilot is unhurt and the flight is considered an impressive demonstration of range and speed for a fighter.^[10]
February 12 – Spanish Nationalist forces have 600 aircraft, compared to only 40 available on the Republican side.^[11]
February 16 – The Spanish Republican Air Force reports that it has only 25 Polikarpov I-15 and I-16 fighters, two squadrons of Tupolev SB-2 bombers, and three squadrons of Polikarpov R-5 bombers.^[12]

Its wreckage is not found until March 4.^[13]

March

To improve coordination of aviation affairs within the United States Army, the United States Department of War places both General Headquarters Air Force (responsible for U.S. Army air combat operations) and the United States Army Air Corps (responsible for aviation logistics and training) under the command of the Chief of the Air Corps, Major General Henry H. Arnold.^[14]

March 18 – During a test flight of a Boeing 307 Stratoliner (registration NX19901) at an altitude of 10,000 feet (3,000 meters), a KLM test pilot attempts a pre-approved test of the aircraft's flying characteristics at low speed with both engines on one side shut down. The Stratoliner stalls, goes into a spin, loses its wings and tail section, and crashes near Alder, Washington, killing all 10 people on board.^[16]
March 25 – Ongoing ceasefire negotiations between Nationalist and Republican officials which include a Nationalist demand that all Spanish Republican Air Force aircraft fly to Nationalist airfields to surrender on this day are broken off when Republican aircraft do not surrender. A major motivation for the Nationalist demand is to prevent Republican leaders from fleeing Spain by air; six Republican aircraft carry officials and refugees from central Spain to France on this day.^[17]

April

April 1
- Nationalist leader Francisco Franco announces that the Spanish Civil War has ended in a complete Nationalist victory. During the 32½-month war, the Nationalists have used about 1,300 aircraft and the Republicans about 1,500; about 10,000 people have died in air attacks. Early Republican numerical air superiority had been challenged almost immediately by the technical superiority of Italian Fiat CR.32 fighters and Savoia-Marchetti SM.81, and German Junkers Ju 52 bomber-transports; Soviet Polikarpov I-15 and I-16 fighters had given the Republicans air superiority in the winter of 1936–1937, but the Nationalists had achieved lasting air superiority after German Messerschmitt Bf 109 fighters and Heinkel He 111 bombers and Italian Savoia-Marchetti SM.79 bombers had arrived in 1937. Germany has sent about 600 aircraft to Spain, Italy about 660, the Soviet Union 1,000, and other countries (principally France) about 350. The German, Italian, and Soviet air forces have learned a great deal about the employment of modern aircraft in warfare through their involvement, and the Luftwaffe's Condor Legion in particular has used the conflict to test new aircraft and revolutionary new air warfare concepts.^[21]^[22]
- The Spanish Republican government airline LAPE ceases operations. The Franco government expropriates LAPE's aircraft and transfers them to the airline Iberia.
- On the ninth anniversary of its founding, the Fieseler aircraft manufacturing company changes its name from Fieseler Flugzeugbau Kassel to the Gerhard Fieseler Werke GmbH.

April 26 – German Luftwaffe Flugkapitän Fritz Wendel sets a new world air speed record, reaching 755.59 km/h (469.50 mph) in the Messerschmitt Me 209 V1 racing aircraft. The German government will report that the record was set by an "Me 109R", a false designation used as part of a 1939 propaganda campaign to confuse other countries into thinking that the Me 209 is an advanced variant of the Messerschmitt Bf 109 fighter.^[19]^[23]
April 28 – Vladimir Kokkinaki and Mikhail Godienko attempt a non-stop flight from the Soviet Union to New York but are forced down on Miscou Island in bad weather the next day.

Serving as a testbed for the Heinkel HeS 3 turbojet with the jet engine slung under its fuselage, a Heinkel He 118 dive bomber takes off and lands using its piston engine but flies under jet power after the turbojet is started in flight. It is the first time any aircraft makes any part of a flight under jet power, and the successful test leads to the first flight made completely under turbojet power by the Heinkel He 178 the following month.^[35]

German Heinkel He 111s attack Ark Royal in the North Sea later in the day, but score no hits.^[48]
September 30 – A series of successful British trial flights to test the concept of using Short C-class flying boats refueled in mid-air by Handley Page Harrow tankers to carry airline passengers across the North Atlantic Ocean is terminated because of the onset of World War II.^[27]

Soviet radio denies that Soviet aircraft bombed Finland, however, claiming that the Soviet Air Force had merely dropped bread to starving people in Helsinki, leading the Finns to refer to Soviet bombs as "Molotov's bread-baskets".^[49] The Soviets have about 800 aircraft committed to the war as it begins, while the entire Finnish Air Force includes only 96 planes, most of them obsolete; one month's worth of aviation gasoline; and a few batteries of antiaircraft artillery.^[50]

December
