• April 12
  • Spartan Air Lines begins flight operations, offering service from Heston Aerodrome outside London to Cowes on the Isle of Wight using three Spartan Cruiser airliners.
  • William Besler makes the first successful flight in a fixed-wing aircraft powered by a steam engine. The aircraft, a Travel Air 2000 biplane, is powered by an oil-fired, reversible 90°-angle V-twin angle-compound engine he and his brother George designed. The seven-minute trial flight is certified by the National Aeronautical Association.[15]
• April 17 – At Oakland Municipal Airport in Oakland, California, George and William Besler unveil their aviation steam engine to the public for the first time, with William flying the steam-powered Travel Air 2000 in a public demonstration that consists of three flights totaling a combined 15 minutes in the air, banking over San Francisco Bay before returning to the airport. The engine is virtually silent, allowing William to call down to the crowd while passing over it at an altitude of 200 feet (61 meters). He reaches 100 mph (161 km/hr) and demonstrates the engine's braking power by reversing the propeller on landing and coming to a stop in only 100 feet (30.5 meters).[16] Despite the engine's success and speculation by aviation reporters that steam engines could economically power the airplanes of the future, the Beslers make no further public flights and do not develop the engine further.[17]

• Erhard Milch, State Secretary of the German Reich Air Ministry, receives a major study of the future of a new German air force written by Dr. Robert Knauss. Knauss projects that the main threat to the reestablishment of Germany as a great power will be a preventive attack by France and Poland before Germany can fully rearm, and he recommends the creation of a force of 400 four-engined bombers which could deter such an attack with an ability to attack enemy population and industrial centers and destroy enemy morale.[20]
• May 7–8 – Stanislaw Skarzynski flies the South Atlantic from Senegal to Brazil in a small single-seater tourist airplane RWD-5bis, in 20 hours 30 minutes, over a distance of 3,582 km (2,226 mi).

Although the flight exceeds the previous record for human altitude – set by Auguste Piccard and Max Cosyns in August 1932 – by 9,077 feet (2,767 meters), the Fédération Aéronautique Internationale (FAI) does not recognize the record as official because the Soviet Union is not an FAI member.[26][29]

October

• Flying a Farman F.239, French aviators Jean Réginensi and André Bailly set three world airspeed records over distances of 100 kilometers (62.1 miles), 500 kilometers (310.5 miles), and 1,000 kilometers (621 miles).

Fordney set a new official world altitude record for human flight in the balloon 'A Century of Progress, reaching 61,237 feet (18,665 meters) before landing near Bridgeton, New Jersey. The altitude is 993 feet (303 meters) lower than that reached by the Soviet balloon USSR-1 in September, but the Fédération Aéronautique Internationale (FAI) had not recognized the Soviet record because the Soviet Union is not an FAI member country.[26]
• November 21 – The only completed Kalinin K-7, which had made its first flight only a little over three months before on 11 August, crashes near Kharkov in the Soviet Union after one of its tail booms suffers a structural failure, killing 15 of the 20 people on board.[32] Although two more K-7s are planned, neither is built before the project is cancelled in 1935.

Competitors are handicapped under an extremely complex scoring system that takes into account fuel consumption, speed of wing folding, comfort, picketing, take off and landing distances, luggage, engine starting, safety appliances, controls and instruments, refueling, ease of maintenance, and a safety criterion that requires them to shut their engines off at an altitude of 2,000 feet (610 meters) and glide to a landing.[34]
