As early as the late 1960s, Stanley Hiller began collecting aircraft at a warehouse in Redwood City, California.[3] Eight years later it had surpassed this and the Hiller Museum of Northern California Aviation Heritage included over 40 aircraft.[8][9] The Michael King Smith Research Library at the museum has a collection of approximately 5,400 books.[10] Exhibits at the museum include flight simulators, a retired British Airways 747 to explore, and an indoor drone plex.[11] The Museum is known for incorporating helicopters to mark holidays, including: The Museum hosts the Biggest Little Air Show, an airshow consisting of radio-control model aircraft ending with a piloted aerobatic demonstration.
