Charles Lindbergh is Hired by the Robertson Aircraft Corporation

In October 1925, Lindbergh was hired by the Robertson Aircraft Corporation (RAC) in St. Louis (where he had been working as a flight instructor) to first lay out, and then serve as chief pilot for the newly designated 278-mile (447 km) Contract Air Mail Route #2 (CAM-2) to provide service between St. Louis and Chicago (Maywood Field) with two intermediate stops in Springfield and Peoria, Illinois. Operating from Robertson's home base at the Lambert-St. Louis Flying Field in Anglum, Missouri, Lindbergh and three other RAC pilots, Philip R. Love, Thomas P. Nelson, and Harlan A. "Bud" Gurney, flew the mail over CAM-2 in a fleet of four modified war surplus de Havilland DH-4 biplanes. Two days before he opened service on the route on April 15, 1926, with its first early morning southbound flight from Chicago to St. Louis, Lindbergh officially became authorized to be entrusted with the "care, custody, and conveyance" of U.S. Mails by formally subscribing and swearing to the Post Office Department's 1874 Oath of Mail Messengers. It would not take long for him to be presented with the circumstances to prove how seriously he took this obligation.
