The Museum of Flight is one of Seattle's unsung treasures. This expansive campus features over 150 air and spacecraft including a Concorde, Air Force One and beginning in 2013, the Space Shuttle Trainer--parts of which are on display as of July 2012. Galleries include a kid's zone, history of flight, rocketry, spacecraft, Boeing company history, WWI and WWII galleries. Plan 3-4 hours for your visit. Picnic on the grounds or eat at the cafe. There are several films as parts of the exhibits, so plan on stopping to view them. The entire campus is wheelchair and stroller safe except for the outdoor aircraft tours. Exhibits are safe for all ages. History buffs will love this place. You will find it clean, welcoming and safe. Those fearing heights may have difficulties going up and down the stairs into the ourdoor aircraft, but they can be viewed from ground level. Parking is free.
