Boeing's largest and most important production facility is located around 50 kilometres north of Seattle. Right next to Paine Field Airport (Snohomish Country Airport), the Boeing 747, 767, 777 and 787 wide-body aircraft are manufactured in the second largest building in the world. As with every visit to Seattle, we went planespotting at the Boeing plant.

The Boeing factory in Everett was completed in 1968 for the final assembly of the legendary Boeing 747. The factory was significantly expanded again to accommodate new aircraft models such as the Boeing 767 in 1980 and the Boeing 777 in 1993. With a volume of 13,385,378 cubic meters, the production hall is currently the second-largest building in the world.
When is the best time for plane spotting at the Boeing factory? The best time to visit is on a weekday. Since most of the flights are test flights, takeoff and landing take place at random times. Your only tool, at least for arriving aircraft, is Flightradar24.
Future of Flight – Planespotting at the Boeing factory

The Future of Flight Museum, with its free Stratodeck observation deck, is an unbeatable location for observing the daily takeoffs and landings on Runway 16R at Paine Field Airport. After all, the museum is located directly across from Boeing's large production halls. If the observation deck is closed, there are a series of hills adjacent to the parking lot, so the annoying chain-link fence won't interfere with plane spotting.
You can find more information about the “Future of Flight” museum and the highly recommended Boeing Tour on the official Website.
If you have enough time, take a drive around the entire airport grounds. There are parking options at various locations. As long as you don't enter the company premises, you won't usually have any trouble with security.
