The museum was founded in 1992 by Mark DiCiero after he built and learned to fly his own helicopter. The museum is a non-profit and all-volunteer organization, with no paid staff. The museum currently has five helicopters in flying condition, which are flown in air displays.
The museum describes its mission as being:
...dedicated to the preservation of rare and vintage rotorcraft. Our mission is to preserve these rotorcraft as a tribute to the pioneers who risked so much to develop vertical flight technology. A key objective is to provide education about, and demonstrate various designs in rotor technology including tandem, co-axial, conventional (single), sync (intermeshing) and tip powered.
Piasecki H-21B - registered N64606, it is the only H-21 still flying today. Built in 1957, the helicopter was obtained by Classic Rotors on January 23, 1990 and restored to flying condition. In 2008 it had an engine failure resulting in an emergency landing in a field at a dairy farm in San Pasqual Valley in California. It was returned to the museum and repaired to flying condition again in October 2009. The cause of the engine failure was a spring on one of the pistons that broke.
