1931 in aviation

This is a list of aviation-related events from 1931:

Events

• Bert Hinkler flies a de Havilland Puss Moth from Canada to New York City, then non-stop 2,400 km (1,500 mi) to Jamaica, then on to British Guiana and Brazil. He then flies across the South Atlantic Ocean to West Africa in extremely bad weather, becoming the first person to fly across the South Atlantic solo and only the second person after Charles Lindbergh in 1927 to fly solo across the Atlantic. He completes his journey by flying from West Africa to London. For the flight, he receives the Segrave Trophy, the Johnston Memorial Prize, and the Britannia Trophy for the most meritorious flying performance of the year.

• January 28 – German explorer Gunther Plüschow and his engineer Ernst Dreblow are killed when their Heinkel HD 24 seaplane crashes near the Brazo Rico (part of Argentino Lake) in Patagonia.

February

They cover 8,168 kilometers (5,075 miles) before higher-than-expected fuel consumption forces them to land only 20 kilometers (12 miles) short of the record.
• February 1 – Polish pilot Stanisław Skarżyński begins a 25,050-kilometer (15,570-mile) tour around Africa in a PZL Ł.2. He will complete it on May 5.

• February 14 – The United States Congress authorizes a new award, the Air Mail Medal of Honor, which the President of the United States is to award to pilots who perform distinguished service in connection with U.S. Air Mail service. It will first be awarded in December 1933.
• February 21 – After a Pan American-Grace Airways (Panagra) Ford Trimotor lands at Rodríguez Ballón Airport at Arequipa, Peru, armed revolutionary soldiers surround it. They demand that it fly them to another destination, but the Trimotor's pilot refuses. The standoff continues for 10 days until, on 2 March, the soldiers suddenly announce that their side won the revolution and let the pilot go in exchange for him giving one of them a ride to Lima.

• March 23–24 (overnight) – The French aviators Joseph Le Brix and Marcel Doret take off from Istres, France, in the prototype Dewoitine D.33 and fly a triangular course from Istres to Montpellier to Nîmes. Although fog forces them to shorten their course during the night of 23–24 March, they remain aloft continuously for 32 hours 17 minutes over a distance of 4,662 kilometres (2,897 mi) at an average speed of 151.36 kilometres per hour (94.05 mph).

• May 28
  • Walter E. Lees and Frederick Brossy set a new endurance record for a non-refueled flight, landing a Bellanca J2 Diesel aircraft at Jacksonville Beach, Florida, after remaining in the air continuously for 84 hours 32 minutes. The record will stand until July 1986.
  • Flying the Pitcairn PCA-2 autogiro Missing Link, John M. Miller completes the first flight across the United States in a rotary-wing aircraft.

  • The Hungarian aviators György Endresz (pilot) and Sándor Magyar (navigator) take off from Harbour Grace, Dominion of Newfoundland, in the Lockheed Model 8A Sirius Justice for Hungary to attempt a nonstop flight to Hungary. Despite thick fog, a compass that jams shortly after takeoff, and a mid-air engine failure, they reach the coast of Ireland in 13 hours 50 minutes — a new world record for a flight between North America and the Irish coast — and fly on toward Hungary, which they reach on 16 July. When the fuel flow to their engine is interrupted they make a forced landing at Bicske, 30 kilometres (19 mi) short of their planned destination at Mátyásföld, and arrive by car at Mátyásföld, where thousands of people greet them. The flight is the 15th successful transatlantic flight and the first to fly nonstop from North America so deep into Europe. It covers 5,770 kilometres (3,585 mi; 3,116 nmi) in 25 hours 20 minutes at a record average speed of 230 kilometres per hour (143 mph). Sponsored by the American-Hungarian Transatlantic Committee to draw attention to what Hungarian Americans view as the injustice of the Treaty of Trianon Hungary signed after its defeat in World War I, the flight also represents the first use of a transatlantic flight for political purposes.
