I am confused. Are there multpile museum of flights by Boeing? I recall researching one which is about 45 minutes outside of downtown Seattle Now I see this one. Are they identical tours?

This is the only "museum of flight," this is in Tukwila about 15 mins south of Seattle. This is the largest Boeing museum with LOTS of airplane models on display, some suspended from the ceiling, some which you can walk on-board and tour etc. This has the original "red barn", and short movies to watch, and a number of interactive exhibits. The other one is the "future of flight" tour which is in Everett (30 mins north of Seattle). That is a smaller "museum" and mostly features a tour of the actual airplane manufacturing facilities. So in general, if you want a museum go to the "museum of flight" 15 mins south of Seattle, if you want a factory tour go to the "future of flight" 30 north of Seattle.

Agreed with the above. "Future of Flight" used to have some cool exhibits on a much smaller scale, but lost those a few years ago due to contract disputes with the facility. It is now just the factory tour, which is impressive, but not a museum.

There is only one museum of flight of Boeing which is in South of Seattle.

Is there a third location? I saw some navtice American sounding city where the other one was
