John Adams Hambleton (1898?-1929) was a recipient of the Croix de Guerre and the Distinguished Service Cross with Oak Leaf Cluster for his service in World War I. In 1927, he joined with Juan Trippe and Cornelius Whitney to form a new service which won the first US International Air Mail contract (1927) for service between Florida and Cuba. The company merged with Pan American Airways (PAA) under a holding company called Pan American Airways Corporation (1927). In 1929, Hambleton made a survey flight to Panama to set up the first airmail flight from the US to the Canal Zone, the inaugural flight of which was made by Charles Lindbergh, with Hambleton serving as copilot. John Hambleton was killed later that year in an aircraft accident.
