The Future of Flight Aviation Center, officially known as Boeing Future of Flight, is an aviation museum and education center located at the northwest corner of Paine Field in Mukilteo, Washington. It is the starting point for the Boeing Tour, a guided tour of a portion of the nearby Boeing Everett Factory in Everett, Washington. The 73,000-square-foot (6,800 m2) facility, owned by Snohomish County via Paine Field and operated by Boeing, opened in 2005 at a cost of $24 million; it is funded by a sales and use tax from the county via its public facilities district. The museum includes a 28,000-square-foot (2,600 m2) gallery containing static and interactive exhibits and displays as well as a 240-seat theater, café and shops.
