# 1938 in aviation

This is a list of aviation-related events from 1938:

## Events

* Imperial Airways inaugurates scheduled service from London to Montreal. Pan American World Airways is banned from British airports out of fears that more advanced U.S. aircraft will drive Imperial out of the transatlantic market.

### March

* March 1 – A Transcontinental & Western Air Douglas DC-2 flying from San Francisco, California, to Winslow, Arizona, crashes in Yosemite National Park in Madera County, California, during bad weather, killing all nine people on board.

* March 7–17 – The Aragon Offensive sees retreating Republican forces bombarded by German Heinkel He 111s and Italian Savoia-Marchetti SM.79s escorted by Messerschmitt Bf 109s and Fiat CR.32s, with German Dornier Do 17 reconnaissance planes assisting in the location of targets.

* May 17 – The United States Congress passes the Naval Expansion Act, leading to the construction of the Essex-class aircraft carriers.

* July 20–21 – The Short S.20 Mercury, flying as a component of the Short Mayo Composite aircraft combination, makes the world's first commercial heavier-than-air crossing of the North Atlantic Ocean, flying non-stop 4,667 km (2,900 mi) from Foynes, Ireland, to Montreal, Quebec, Canada, with a 454 kg (1,001 lb) payload.

* July 24 – Disaster strikes when a Colombian Air Force pilot performing an aerobatic display in a Curtiss Hawk II biplane fighter at a military review at Campo de Marte, Santa Ana, Usaquén, Colombia, disregards orders to remain above 500 feet (150 meters) and attempts to fly between the camp's presidential grandstand and diplomatic grandstand. His wingtop strikes the diplomatic grandstand, and his aircraft careens into the presidential grandstand, destroying part of its roof, before crashing into a crowd of spectators on the ground between the two grandstands, bursting into flames and sliding through them before coming to a stop upside down. An estimated 50 to 75 people are killed, and another 100 people – including future President of Colombia Misael Pastrana Borrero – are injured. Outgoing Colombian President Alfonso López Pumarejo and his successor Eduardo Santos are in the presidential grandstand but avoid injury.

The test is a success, and the flight marks the first use of a modern American aviation oxygen mask.
** The British Empire's Empire Air Mail Scheme, in which Imperial Airways carries all first-class mail by air, begins service to Australia, using a Qantas connection forward from Singapore; Short Empire flying boats are used throughout.
* July 29

* By the beginning of August, Nationalist fighters appear in sufficient numbers to establish Nationalist air superiority over the battlefield in the Battle of the Ebro. Inadequate Republican antiaircraft artillery, poor management of Republican fighters, the death of many Republican pilots, and the withdrawal of many of the best Soviet pilots from Spain all allow Nationalist aircraft to operate largely unchallenged. Up to 200 Nationalist aircraft circle over the battlefield as Nationalist forces begin a counteroffensive, shooting down many Republican fighters and dropping an average of 10,000 pounds (4,500 kg) of bombs per day into September. Small targets prove difficult for Nationalist aircraft to hit.

Chkalov is thrown from the cockpit ad dies of his injuries two hours later. The crash deals a blow to aircraft designer Nikolai Nikolaevich Polikarpov′s reputation with Josef Stalin and effectively ends his career.
* December 29–31 – A German Arado Ar 79 training and touring aircraft sets an international long-distance record for an aircraft of its class, flying 6,303 km (3,917 statute miles) from Benghazi, Libya, to Gaya, India, nonstop at an average speed of 160 km/h (99 mph).
