The Historic Flight Foundation (HFF) is an aviation museum located at Felts Field in Spokane, Washington. The museum collects, restores, and flies historic aircraft from the period between Charles Lindbergh’s solo Atlantic crossing in 1927 and the first commercial flight of the Boeing 707 in 1957, a 30-year period when airplanes evolved from relatively simple wood and fabric biplanes to commercial jets. The museum was previously located at Paine Field in Mukilteo, Washington, but was relocated to Spokane during the spring of 2020 due to the presence of commercial air service at Paine Field.
