The Historic Flight Foundation (HFF) was an aviation museum located at Felts Field in Spokane, Washington.

The museum collected, restored, and flew 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.

Two of Historic Flight's aircraft won awards for their restoration work at the National Aviation Heritage Invitational at the California Capital Airshow in September 2017.

In 2006 the museum began planning the construction of the hangar at Paine Field that initially housed the foundation's aircraft collection.

[9][10] However, with the museum unable to cope with the demands of then-new commercial air service at Paine Field, it elected to move all of its collection to Spokane during the spring of 2020, with the Mukilteo location reduced to maintenance and restoration duties.

The collection also included aviation artifacts such as military uniforms and vintage flight suits, as well as several vintage cars and buses, including a 1927 Cadillac Touring Phaeton car in which President Franklin Delano Roosevelt toured Glacier National Park on August 5, 1934.
