The Museum of Flight is a private non-profit air and space museum in the northwest United States. It is located at the southern end of Boring field - offically known as King County International Airport where most Boeing aircraft fly out to clients.

Wide body jets are built further north at Boeing Everett.

It is in the city of Tukwila, just south of Seattle. It was established in 1965. As the largest private air and space museum in the world, it attracts a lot of visitors (supposedly 400,000 visitors) every year. The museum serves more than 140,000 students yearly through both its onsite programs: a Challenger Learning Center, an Aviation Learning Center, and a summer camp (ACE), as well as outreach programs that travel throughout Washington and Oregon. Not all the aircraft are originals, but the collection is very impressive. On the other hand it has a lack of Airbus aircraft for some reason
