Its exhibits include the Hughes H-4 Hercules (Spruce Goose) and more than fifty military and civilian aircraft, unmanned aerial vehicles (drones), and spacecraft.

The museum is located across the highway from the former headquarters of Evergreen International Aviation and across Oregon Route 18 from McMinnville Municipal Airport (KMMV).

In March 1990, The Walt Disney Company announced that it would close the Long Beach, California, exhibit of the Spruce Goose.

[8] A deal was reached four months later for the museum to purchase 25 aircraft from a bankrupt for-profit corporation with the assistance of the Collings Foundation and a developer from Maine named George Schott.

[13] In July 2016, the space building and waterpark were purchased for $10.9 million by The Falls Event Center, a company owned by Steve Down.

Other aircraft, spanning the entire history of aviation, are arranged in the building, some parked under the wings of the Spruce Goose or suspended from the ceiling.

Because there are fewer space-related holdings, the center includes a large number of panels and other displays that chronicle the history of space flight.

[citation needed] Two of the main attractions of the space flight center are a Titan II SLV satellite booster rocket and a SR-71 Blackbird.

[18] The Titan II sits upright in a specially constructed display extending two stories below the floor, in order to fit the 114 foot tall rocket inside the building.

The exhibit includes a re-created Titan II SLV Launch Control Room outfitted with actual furnishings and equipment donated from Vandenberg Air Force Base.

[19] A smaller building contains the Evergreen Digital theater featuring a seven-story wide by six-story tall screen and multi-channel surround sound.

[20] The 71,350-square-foot (6,629 m2) waterpark, Oregon's largest, features 10 slides and a 91,703-gallon wave pool with the intent of tying into the educational focus of the Evergreen Museum Campus with its "Life Needs Water" interactive display in the H2O Children's Science Center.
