Fodor's Expert Review Boeing Future of Flight

The vast 98-acre campus where the Boeing Everett line (767, 777, and 787 Dreamliner) is produced holds the world's largest building—so big that it often creates its own weather system inside. At the start of the pandemic, factory tours were halted, and as of this writing, there's no timeframe regarding their return. Visitors can still visit an enormous gallery with cutaways of airplane fuselages, up-close looks at the inner workings of navigation and hydraulic systems, and interactive exhibits on satellites, submarines, and space travel. You can even walk inside a space station module that was launched on an actual space shuttle mission. There's also a café, a kid-oriented family zone, and the Sky Deck atop the building, where you're treated to views of jets taking off and landing at adjacent Paine Field and impressive views of the surrounding mountains and Puget Sound.
