Materials contain photographs of the Hughes XF-11 prototype military reconnaissance aircraft. Howard Hughes piloted the two XF-11 prototypes built: in July 1946, Hughes crashed the first XF-11 in Beverly Hills, California; in April 1947, Hughes successfully flew the second prototype at high speeds and at high altitudes. However, the United States Air Force abandoned the controversial project, and in August of 1947, Hughes was called to testify before the Truman Committee in the U.S. Senate about the failures of the program.

Materials contain photographs of the Hughes H-1 Racer aircraft from 1935 to 1945. The photographs primarily depict Howard Hughes standing with the plane or in the plane's cockpit. The plane was designed by Glenn Odekirk and built by Hughes Aircraft Company in 1935, the first plane produced by the company. Hughes broke several records in the H-1, including the landplane speed record in 1935. In 1937, Hughes broke his own transcontinental speed record by flying from Los Angeles, California to New York City, New York in 7 hours, 28 minutes. Despite its speed, Hughes was unable to sell the H-1 to the U.S. military.
