In 1929, Jimmy Doolittle developed flight instruments . 1929 also saw the first flight of by far the largest plane ever built until then: the Dornier Do X with a wingspan of 48 m. On its 70th test flight on 21 October 1929, there were 169 people on board, a record that was not broken for 20 years.
In 1923, The first successful rotorcraft appeared in the form of the autogyro, invented by Spanish engineer Juan de la Cierva and first flown in 1919. In this design, the rotor is not powered but spins freely as it moves through the air, while a separate engine powers the aircraft to move forward. This was the basis of further development and prototypes that led to the creation of the helicopter. In 1930 Corradino D'Ascanio, an Italian engineer, developed a coaxial helicopter with the important inclusion of three small propellers on the craft, which controlled the pitch, roll, and yaw of the aircraft. Later helicopters saw several adjustments to their rotors but the first modern helicopter was not constructed until 1947 by Igor Sikorsky
Only five years after the German Dornier Do-X had flown, Tupolev designed the largest aircraft of the 1930s era, the Maksim Gorky in the Soviet Union by 1934, as the largest aircraft ever built using the Junkers methods of metal aircraft construction.
In the 1930s, development of the jet engines began in Germany and in Britain and they began testing in 1939 before World War II. The jet engine saw considerable development during the war, with a few jet powered aircraft being used in the war.

After enrolling in the Military Aviation Academy in Eskisehir in 1936 and undertaking training at the First Aircraft Regiment, Sabiha Gökçen, flew fighter and bomber planes becoming the first Turkish, female aviator and the world's first, female, combat pilot. During her flying career, she achieved some 8,000 hours, 32 of which were combat missions.

=== World War II (1939–1945) ===

World War II saw a great increase in the pace of development and production, not only of aircraft but also the associated flight-based weapon delivery systems. Air combat tactics and doctrines started being rapidly developed. Large-scale strategic bombing campaigns were launched, fighter escorts introduced and the more flexible aircraft and weapons allowed precise attacks on small targets with dive bombers, fighter-bombers, and ground-attack aircraft. New technologies like radar also allowed more coordinated and controlled deployment of air defence.

The first jet aircraft to fly was the Heinkel He 178 (Germany), flown by Erich Warsitz in 1939, followed by the world's first operational jet aircraft, the Messerschmitt Me 262, in July 1942 and world's first jet-powered bomber, the Arado Ar 234, in June 1943. British developments, like the Gloster Meteor, followed afterwards, but saw only brief use in World War II. The first cruise missile (V-1), the first ballistic missile (V-2), the first (and to date only) operational rocket-powered combat aircraft Me 163—which attained velocities of up to 1,130 km/h (700 mph) in test flights—and the first vertical take-off a manned point-defence interceptor, the Bachem Ba 349 Natter, were also developed by Germany. However, jet and rocket aircraft had only limited impact due to their late introduction, fuel shortages, the lack of experienced pilots and the declining war industry of Germany.
Not only aeroplanes, but also helicopters saw rapid development in the Second World War, with the introduction of the Focke Achgelis Fa 223, the Flettner Fl 282 synchropter in 1941 in Germany and the Sikorsky R-4 in 1942 in the USA.

=== Postwar era (1945–1979) ===

Following World War II, commercial aviation expanded quickly, primarily relying on former military aircraft to carry passengers and cargo. There was an excess of large bombers, such as the B-29 and Lancaster, which were easily converted for commercial use. The DC-3 specifically played a key role, enabling longer and more efficient flights.
