Yuma Crossing
Immediately after the Mexican–American War in 1848, the U.S. Army built Fort Yuma here to protect travelers from Indians raiding the area. It was the center point of conflict in the Yuma War of 1850–53. From 1864–1890, the fort and nearby facilities was the main army base to support the US Army's efforts to control the Indians throughout the greater southwest.
Yuma International Airport
In 1929, Yuma was selected as the first stop for the Women's Transcontinental Air Race. Amelia Earhart experienced landing problems and nosed her aircraft in the soft sand, destroying her propeller. A new propeller and mechanics were flown in from Los Angeles to make repairs so she could continue in the race. Fly Field experienced a downturn during the depression; but in the late 1930s it became clear that the United States faced a threat of conflict with the German Reich. The War Department needed facilities to train combat pilots and crews. Planning for the Yuma area, including a potential bombing range located between Yuma and Gila Bend, started in 1939 when a group of aeronautical experts toured the area. The Yuma County Board of Supervisors recommended Fly Field as a base for the Army Air Corps. Initially, Yuma County assumed the burden of airfield maintenance and limited the use exclusively to Army and Navy aircraft.
