At one point, their Savoia-Marchetti S.55flying boatSanta Maria is towed by a Brazilian river boat for 200 miles (320 kilometers) along the Paraguay River in search of a suitable takeoff area after a refueling stop, and it takes them until March 20 to complete their crossing of the Matto Grosso and land at Manaós, Brazil. It is history's first flight over the Mato Grosso.[5]

Departing Paris on 20 April, they have followed the route Paris-Belgrade-Aleppo-Basra-Jask-Karachi-Bombay-Karachi-Jask-Basra-Aleppo-Belgrade. They make the flight to spur interest in investment in the Kingdom of Yugoslavia′s first civilian airline, Aeroput. Investment in Aeroput increases greatly, saving the new airline from abolition due a lack of capital.[citation needed]
May 4 – United States Army Air CorpsCaptainHawthorne C. Gray sets an unofficial record for the highest altitude reached by a human being, attaining 42,470 feet (12,940 meters) in a balloon with an open basket over Belleville, Illinois. Because of the rapid descent of the balloon, he parachutes out at 8,000 feet (2,400 meters), disqualifying him from recognition for an official record by the Fédération Aéronautique Internationale (FAI), which requires that a balloonist land with his craft in order to set an official record.[7][8][9]
May 20 – The Dominion of Newfoundland Post Office issues history's first postage stamp honoring an individual aviator. It honors Francesco de Pinedo.[14]
May 22–23 – Pinedo, Del Prete, and Zacchetti depart Trepassey Bay in the Dominion of Newfoundland, planning to cross the Atlantic Ocean to the Azores, refuel, and then fly on to Portugal, retracing the transatlantic flight route of the United States NavyCurtiss NC-4 flying boat in 1919, but they run low on fuel due to unfavorable weather. Pinedo is forced to land the Santa Maria II on the ocean and be taken under tow by a Portuguese fishing boat and an Italian steamer for the final 200 miles (320 km) to the Azores, where the plane arrives at Horta on May 30.[5][15]
May 28 – While flying at 1,200 feet (370 meters) near Reynoldsburg, Ohio, the United States Army Air Service's Keystone XLB-5 bomber prototype suffers a failure of its right engine in which a blade separates from the propeller hub with explosive power, tearing the engine apart and spraying the five-man crew – which includes 2nd Bombardment Group commander Lewis H. Brereton – with shrapnel. The nose gunner is killed, but the other four men aboard parachute to safety. The gasoline-soaked wreckage of the aircraft explodes and burns on the ground.

Flying in a balloon with an open basket in an attempt to set an official world altitude record for human flight – his altitude records of March and May having been unofficial – United States Army Air CorpsCaptainHawthorne C. Gray dies of hypoxia after his balloon reaches 40,000 feet (12,000 meters). His body is found in his balloon basket in a tree near Sparta, Tennessee, the next day. His balloon's barograph indicates that the balloon reached between 43,000 and 44,000 feet (13,000 and 13,000 meters) before descending.[7][8][9][27] No further high-altitude balloon fights in open baskets will be attempted until the United States Air Force begins Project Manhigh in 1955.[28]
November 21 – During an air show at Santa Monica, California, parachutist Jean West's parachute becomes entangled on the wing of the plane she jumped from. The pilot manages to land the plane safely, dragging West for several hundred feet, but she nonetheless escapes the incident uninjured.[29]
