The years between World War I and World War II saw great advancements in aircraft technology. Airplanes evolved from low-powered biplanes made from wood and fabric to sleek, high-powered monoplanes made of aluminum, based primarily on the founding work of Hugo Junkers during the World War I period and its adoption by American designer William Bushnell Stout and Soviet designer Andrei Tupolev. After World War I, experienced fighter pilots were eager to show off their skills. Many American pilots became barnstormers, flying into small towns across the country and showing off their flying abilities, as well as taking paying passengers for rides. Eventually, the barnstormers grouped into more organized displays. Air shows sprang up around the country, with air races, acrobatic stunts, and feats of air superiority. The air races drove engine and airframe development—the Schneider Trophy, for example, led to a series of ever faster and sleeker monoplane designs culminating in the Supermarine S.6B. With pilots competing for cash prizes, there was an incentive to go faster. Amelia Earhart was perhaps the most famous of those on the barnstorming/air show circuit. She was also the first female pilot to achieve records such as the crossing of the Atlantic and Pacific Oceans. Prizes for distance and speed records also drove development forwards. On 14 June 1919, Captain John Alcock and Lieutenant Arthur Brown co-piloted a Vickers Vimy non-stop from St. John's, Newfoundland to Clifden, Ireland, winning the £13,000 ($65,000). Northcliffe prize. Commercial aviation was introduced by Aircraft Transport and Travel (AT&T) in Britain, which began the first regular scheduled international flight in 1919. The first flight across the South Atlantic and the first aerial crossing using astronomical navigation, was made by the naval aviators Gago Coutinho and Sacadura Cabral in 1922, from Lisbon, Portugal, to Rio de Janeiro, Brazil, using an aircraft fitted with an artificial horizon for aeronautical use. In 1924, Major General Mason Patrick led a group of U.S. Army Air Service members to complete the first aerial circumnavigation of the world. This flight around the world came with many logistical challenges, traveling 26,343 miles over the span of 175 days. This flight led to improved foreign relations by promoting commercial collaboration, and greater public interest in aviation, prompting governments to put more resources into developing their aviation forces. On 21 May 1927, Charles Lindbergh received the Orteig Prize of $25,000 for the first solo non-stop crossing of the Atlantic. This caused what was known in aviation at the time as the "Lindbergh boom", which increased public interest in aviation. Australian Sir Charles Kingsford Smith was the first to fly across the larger Pacific Ocean in the Southern Cross. His crew left Oakland, California to make the first trans-Pacific flight to Australia, making three stops to complete the journey. Kingsford-Smith and his crew made their first stop in Hawaii from Oakland, California, and from Hawaii to Suva, Fiji. During the last segment of their journey from Fiji to Brisbane, Australia, they encountered severe thunderstorms, and were thrown nearly 140 miles off their course. The flight concluded on 9 June 1928 after flying 7,230 miles, Kingsford-Smith and his crew landed in Brisbane, Australia, receiving $25,000 from the Australian government for their achievement. Accompanying him were Australian aviator Charles Ulm as the relief pilot, and the Americans James Warner and Captain Harry Lyon (who were the radio operator, navigator and engineer). A week after they landed, Kingsford Smith and Ulm recorded a disc for Columbia talking about their trip. With Ulm, Kingsford Smith later continued his journey being the first in 1929 to circumnavigate the world, crossing the equator twice. The first lighter-than-air crossings of the Atlantic were made by airship in July 1919 by His Majesty's Airship R34 and crew when they flew from East Lothian, Scotland to Long Island, New York and then back to Pulham, England. By 1929, airship technology had advanced to the point that the first round-the-world flight was completed by the Graf Zeppelin in September and in October, the same aircraft inaugurated the first commercial transatlantic service. However, the age of the rigid airship ended following the destruction by fire of the zeppelin LZ 129 Hindenburg just before landing at Lakehurst, New Jersey on 6 May 1937, killing 35 of the 97 people aboard. Previous spectacular airship accidents, from the Wingfoot Express disaster (1919), the loss of the R101 (1930), the Akron (1933) and the Macon (1935) had already cast doubt on airship safety. The disasters of the U.S. Navy's rigids showed the importance of solely using helium as the lifting medium. Following the destruction of the Hindenburg, the remaining airship making international flights, the Graf Zeppelin was retired (June 1937). Its replacement, the rigid airship Graf Zeppelin II, made a number of flights, primarily over Germany, from 1938 to 1939, but was grounded when Germany began World War II. Both remaining German zeppelins were scrapped in 1940 to supply metal for the German Luftwaffe air force. Meanwhile, Germany, which was restricted by the Treaty of Versailles in its development of powered aircraft, developed gliding as a sport, especially at the Wasserkuppe, during the 1920s. In its various forms, in the 21st-century sailplane aviation now has over 400,000 participants.
