Don't even think of Boeing (Seattle), complete waste of time if you want to see aircraft in construction. Great museum though.
What is your exact issues with the Boeing tour?
I took the Everett tour and found it very interesting, the bus journey to the actual factory passed numerous aircraft at various stages and inside the factory we had an overview of the 777 production line, I believe now it overlooks the 787 line too? But someone will need to verify this.
So i'm confused by your statement that it's a waste of time!?
Spru!
