It remains both the longest non-stop flight by a piston-engined fighter and the fastest Hawaii-to-New York City flight by a piston-engined aircraft in history.

March

• March 3 – In Naval Strategic Planning Study 3, the Strategic Plans Division of the Office of the Chief of Naval Operations asserts that U.S. Navy aircraft carriers will be able to operate successfully against the coast of the Soviet Union in the face of substantial land-based Soviet air power, stating that the carriers are "the only weapon in the possession of the U.S. which can deliver early and effective attacks against Russian air power and selective shore objectives in the initial stages of a Russo-American conflict." The findings anger U.S. Air Force planners, who view strategic attacks against the Soviet Union as a strictly Air Force mission.

• May 29
  • A United States Army Air Forces Douglas C-54D Skymaster crashes on approach to Naval Air Station Atsugi, Japan, at the end of a flight from Kimpo Airport in Seoul, South Korea, killing all 41 people on board. It is the worst aviation accident in Japanese history at the time.
  • A Flugfélag Islands Douglas C-47A-25-DK on a domestic flight in Iceland from Reykjavík Airport in Reykjavík to Akureyri Airport in Akureyri flies into the side of Hestfjall Mountain at the side of Hédinsfjördur, killing all 25 people on board. The wreckage is found the following day.
  • The Douglas DC-4 Mainliner Lake Tahoe, operating as United Airlines Flight 521, fails to become airborne while attempting to take off from LaGuardia Airport in New York City, runs off the end of the runway, and slams into an embankment, killing 42 of the 48 people on board. It is the worst aviation disaster in American history at the time, although the death toll will be exceeded in a crash the following day.
• May 30 – During a flight from Newark, New Jersey, to Florida, an Eastern Air Lines DC-4 disintegrates in flight at an altitude of 6,000 feet (1,800 m) and crashes into a swamp near Baltimore, Maryland, killing all 53 people on board. It replaces the previous day's United Airlines crash as the deadliest airline accident in American history. Among the dead are two relatives of a man who had died the previous day in the United crash. The 97 deaths in the two crashes exceed the entire commercial aviation death toll in the United States for 1946.

June

• June 4 – Orient Airways, the first and only Muslim-owned airline in the British Raj, begins flight operations.
• June 17 – Pan American World Airways inaugurates what are considered the world's first scheduled commercial round-the-world flights, although the service actually operates between New York City and San Francisco without crossing the continental United States. Flight One, operated by a Douglas DC-4, departs San Francisco and stops at Honolulu, Hawaii; Midway Atoll; Wake Island; Guam; Manila, the Philippines; Bangkok; and Calcutta, where it meets Flight Two, a Lockheed Constellation that had flown from LaGuardia Airport in New York City. In Calcutta, the two aircraft swap flight designations; the DC-4 then turns back and continues as Flight Two to San Francisco, while the Constellation turns back and continues as Flight One, stopping at Karachi; Istanbul; London; Shannon, Ireland; and Gander, Newfoundland before arriving at LaGuardia Airport.
• June 19
  • Pan American Airways Flight 121, the Lockheed L-049 Constellation Clipper Eclipse (registration NC88845) carrying 36 people on a flight from Karachi Airport in Karachi, British India, to Istanbul-Yesilköy Airport in Istanbul, Turkey, feathers its number one propeller due to engine problems, then suffers overheating in its other three engines. As it descends, the number two engine nacelle catches fire and the engine detaches from the airliner, which makes a belly landing near Mayadin, Syria. Fourteen of the people on board die; it is the worst aviation accident in Syrian history at the time. Future Star Trek creator Gene Roddenberry is among the survivors.
  • United States Army Air Forces Colonel Albert Boyd sets a new official world airspeed record of 623.62 mph (1,003.62 km/h) in a Lockheed P-80 Shooting Star. (This is still marginally slower than unofficial German speed records in rocket-powered aircraft during World War II).
• June 22 – At the Wilson-King Sky Show in St. George, Utah, a light plane involved in the air show experiences brake failure on landing and crashes into cars parked at the edge of the airfield, killing a teenaged girl. The pilot and the dead girl's mother and infant sister are injured.
• June 24 – Kenneth Arnold UFO sighting: American businessman and aviator Kenneth Arnold is piloting a CallAir A-2 at about 9,200 feet (2,800 m) near Mineral, Washington (near Mount Rainier) when he sights what he reports to be a group of disc-like unidentified flying objects flying in a chain which he clocks at a minimum of 1,200 mph (1,900 km/h). He refers to them as looking like saucers, leading the press to coin the term "flying saucer," which soon enters everyday speech.
• June 30 – The Evaluation Board for Operation Crossroads submits its final report on the July 1946 atomic bomb tests at Bikini Atoll. It finds that an atomic attack could go beyond stopping a country's military effort and in addition wreck its economic and social structure for lengthy periods, and could even depopulate large portions of the earth's surface, threaten the existence of civilization, and cause the extinction of mankind. It recommends that the United States develop a large inventory of atomic weapons and the means to deliver them promptly and be prepared to strike first, with legal authority to launch a massive atomic strike to preempt a foreign strike if there are indications that an adversary is preparing one.

July

• July 26 – President of the United States Harry S. Truman signs the National Security Act of 1947, creating the United States Department of Defense. Among its many provisions is one which states that the soon-to-be established United States Air Force "shall include aviation forces both combat and service not otherwise assigned." This wording allows the U.S. Navy and U.S. Marine Corps to retain their aviation forces upon the establishment of the independent Air Force in September 1947.
• July 29 – In the Netherlands East Indies, the three surviving aircraft of the Indonesian Air Force bomb Dutch forces at Ambarawa, Salatiga, and Semarang, disproving the Dutch claim of having destroyed the entire Indonesian Air Force.
