December 21, 1926

1926: Maj Herbert A. Dargue led a Pan Am goodwill flight from San Antonio around South America to Washington DC. For the 22,065-mile flight, Major Dargue used five Loening Amphibians with 420-horsepower Liberty engines. On 2 May 1927, 4 aircraft and 8 of 10 aviators (including Capt Ira C. Eaker and 1Lt Muir S. Fairchild) completed the flight. They received the Mackay Trophy and DFCs for their effort. Unfortunately, the fourth plane crashed in Argentina, killing the crewmen.
