1946 in aviation

This is a list of aviation-related events from 1946:

Events

 * The American Section of the International League of Aviators resurrects the National Trophy, a Harmon Trophy awarded from 1926 to 1938 to the outstanding aviator of the year in each of the 21 member countries of the now-defunct League. It will be awarded until 1949 amid much controversy, with the awards going largely unrecognized.
 * The Electric Boat Company purchases Canadair from the Government of Canada, an important step toward the 1952 founding of General Dynamics Corporation.
 * The Bureau d'Enquêtes et d'Analyses pour la Sécurité de l'Aviation Civile (BEA), or Bureau of Investigation and Analysis for Civil Aviation Safety, is formed as the French government agency responsible for investigating aviation accidents and incidents and making safety recommendations based on what is learned from those investigations.
 * The Nicaraguan airline LANICA begins flight operations.

January

 * Aeropostal Alas de Venezuela (LAV) inaugurates its second international route, offering service between Venezuela and Aruba in the Netherlands East Indies. The route connects LAV with KLM′s international route structure.
 * January 1
 * A British South American Airways Avro Lancastrian becomes the first commercial flight to depart from London Heathrow Airport.
 * East African Airways begins flight operations.
 * Middle East Airlines begins flight operations, flying three de Havilland DH.89A Dragon Rapides between Beirut, Lebanon, and Nicosia, Cyprus.
 * January 6 – Pennsylvania Central Airlines Flight 105, a Douglas DC-3-393, crashes while landing at Birmingham Municipal Airport in Birmingham, Alabama, killing three and injuring five of the 19 people on board.
 * January 8 – The U.S. Joint War Plans Committee reports that by July 1946, as a result of post-World War II demobilization, the United States Army Air Forces will have only five heavy bomber groups in Europe, with only a 65-percent readiness level, and a reserve force of five heavy bomber groups in the United States, with only a 20-percent readiness level. It also reports that the United States Navy will have 13 aircraft carriers at a high state of readiness by that time. It finds that in the event of war with the Soviet Union, the only effective American response will be the delivery of atomic bombs by aircraft of the U.S. Army Air Forces and the United States Navy, and recommends atomic strikes by Army Air Forces B-29 Superfortress bombers based in England; Foggia, Italy; Agra, India; and Chengdu, Republic of China, on 17 Soviet cities to target administrative and research and development centers and aircraft and munitions factories, with an expectation of a B-29 loss rate of 35 percent. It recommends an inventory of 196 atomic bombs in order to carry out this campaign.
 * January 10 – A Sikorsky R5 sets an unofficial helicopter altitude record of 6,400 m at Stratford, Connecticut.
 * January 12 – The U.S. Joint Chiefs of Staff note that the use of atomic bombs alone will be insufficient to defeat the Soviet Union in the event of a war, and that substantial conventional air, ground, and naval forces will remain necessary.
 * January 14 – Pan American Airways becomes the first airline to offer transatlantic Lockheed Constellation service, beating its rival Transcontinental & Western Air in providing transatlantic Constellation service by three weeks.
 * January 18 – The most decorated United States Navy ship of World War II, the aircraft carrier USS Enterprise (CV-6), arrives at Bayonne, New Jersey, completing the second of her two round-trip voyages between the New York City area and Southampton, England, to bring American military personnel back to the United States as part of Operation Magic Carpet. She never puts to sea again.

 * February 4 – Pan American Airways begins its first transatlantic landplane service, scheduling seven Douglas DC-4 flights per week from LaGuardia Airport in New York City to Hurn Airport at Bournemouth in England and two per week between LaGuardia Airport and Lisbon, Portugal. The flights to Bournemouth take 17 hours 40 minutes one-way and those to Lisbon take 20 hours 45 minutes one-way. The flights are a great advance over Pan Am's one-every-two-week Boeing 314 flying boat service from LaGuardia to Lisbon, which requires 29 hours 30 minutes one way, and the airline soon ends flying boat service.
 * February 5 – Transcontinental and Western Air, the future Trans World Airlines, inaugurates its first international service, using Lockheed Constellations on the route New York City–Gander, Newfoundland–Shannon, Ireland–Paris, France.

 * May 20 – A United States Army Air Forces Beechcraft C-45F Expediter flying in fog from Lake Charles Army Air Field in Louisiana to Newark Airport in Newark, New Jersey, crashes into the north side of 40 Wall Street in New York City, striking the 58th floor. The crash creates a 20-by-10-foot (6.1-by-3-meter) hole in the masonry and kills all five people aboard the plane, one of them a Women's Army Corps officer. No one on the street below and none of the 2,000 people in the building are injured.
 * May 27 – In United States v. Causby, the United States Supreme Court rules that the common law doctrine that persons who own real property own it Cuius est solum, eius est usque ad coelum et ad inferos ("from the depths to the heavens") "has no place in the modern world" at least as far as air rights are concerned, but that it remains "fundamental to property rights in land" as a source of law, and therefore a landowner does own "at least as much of the space above the ground as he can occupy or use in connection with the land" and invasions of that airspace "are in the same category as invasions of the surface." The ruling entitles the plaintiff to collect damages from the United States Government under the takings clause of the Fifth Amendment of the United States Constitution for forcing him out of the business of raising chickens on his farm because of the negative effect on the chickens of U.S. military aircraft operating from a nearby airport, but it does not specifically define where private property rights end and public airspace begins over private property in the United States.
 * May 31 - London Heathrow Airport is officially opened.

 * The U.S. Navy establishes Experimental Squadron 3 (VX-3). Equipped with Piasecki HRP-1 Rescuer helicopters, it probably is the world's first official all-helicopter squadron.
 * With post-World War II demobilization well underway, the U.S. Navy's force of aircraft carriers has dropped to 23 of all types with more decommissionings planned, while its aircraft force has declined from 41,000 to 24,000 within the past year and continues to decline rapidly.
 * July 4 – The aircraft carriers USS Antietam (CV-36) and USS Boxer (CV-21) are among ten U.S. Navy ships participating in the celebration at Manila of the independence of the Republic of the Philippines.
 * July 11 – A fire begins in the baggage compartment of the Transcontinental and Western Airways Lockheed L-049 Constellation Star of Lisbon during a training flight with no passengers on board designated Flight 513.

It recommends that the United States develop air warning, air defense, and antiaircraft artillery systems with which to counter such operations.
 * August 9 – As three U.S. Army Air Forces A-26 Invader attack aircraft make a low-level pass during an air show at the North Montana State Fair in Great Falls, Montana, two of them collide 750 ft from a grandstand crowded with 20,000 spectators. The wing of one A-26 shears off the tail of the other. The tail-less A-26 crashes into a horse barn, killing three crew members, three people on the ground, and twenty thoroughbred horses; the other A-26 continues to fly for between one and five miles (1.6 and 8 kilometers) (sources differ) before crashing in a field, killing one of its crewmen. The third bomber in the formation lands safely.
 * August 15 – The U.S. Joint Warfare Planning Committee submits Plan Gridle for the defense of Turkey against the Soviet Union, which finds that the Turkish Air Force of fewer than 700 aircraft could offer only token resistance against a Soviet offensive and would have to be reinforced by ten American fighter groups, followed by the establishment of U.S. Army Air Forces heavy bomber bases in Turkey.
 * August 23 – The U.S. Joint Intelligence Staff assesses that by 1948 the Soviet Union will be able to deploy 2,000 bombers against sea lines of communication in the Mediterranean Sea.

On take-off, it weighs 85,575 lb, the heaviest twin-engine aircraft ever to take off up to this time. Although bad weather forces the plane to land short of Washington in Columbus, Ohio, after 55 hours 17 minutes continuously in the air, the flight nonetheless sets a new nonstop, unrefueled world distance record of 11,235.6 nmi which stands for 16 years until broken by a U.S. Air Force B-52H Stratofortress in 1962.

October

 * Under pressure from Pan American Airways, the Government of Mexico suspends the operating permit for the airline Aerovias Braniff, which has operated only since March 1945.

 * October 3 – Carrying mostly wives and children of United States Army personnel serving in Germany, the American Overseas Airlines Douglas DC-4 Flagship New England crashes into a mountainside shortly after taking off from Stephenville in the Dominion of Newfoundland bound for Shannon Airport in Ireland, killing all 39 people on board. It is the worst U.S. civil airline accident in history at the time.
 * October 15 – Hermann Göring commits suicide by poisoning himself in his jail cell at Nuremberg, Germany, the day before his scheduled hanging for war crimes.

 * November 6 – An American intelligence report predicts that by 1956 the Soviet Union will have a strategic air force and as many as 150 atomic bombs, while the United States will have 350 to 400 atomic bombs. It assesses that the Soviet Union would withhold its atomic weapons during a war in order to deter an American nuclear attack on Soviet targets.
 * November 10 – A U.S. Army Air Forces C-53 Skytrooper crashes on Switzerland's Gauli Glacier, posing a challenge for an assemblage of rescuers from the United States and the United Kingdom and Swiss aviators in spotting the downed plane.

 * December 24 – Western Air Lines Flight 44, a Douglas DC-3A (registration NC45395) crashes into the east slope of Cayupaipe Mountain in the Laguna Mountains while descending to a landing at Lindbergh Field in San Diego, California, towards the end of a flight from Holtville Airport, in Holtville, California, killing all 12 people on board.
 * December 25 – Three passenger planes, all flying in from Chongqing, China, crash due to fog in separate incidents in Shanghai, China, killing at least 62 of the combined 68 passengers and 9 crew members aboard. Two of the planes belong to China National Aviation Corporation and one to Central Air Transport. The incident became known as the Black Christmas disaster.
 * December 30 – A United States Navy PBM Mariner supporting Operation Highjump crashes at Thurston Island, Antarctica, during a blizzard, killing three of the nine people on board. The six survivors are rescued 13 days later by aircraft from the U.S. Navy seaplane tender USS Pine Island (AV-12).
 * December 31
