Was in Seattle this weekend and we went to the Boeing plant in Everett. Unfortunately, they don't allow cameras on the tour but I got this pic of one of the four Dreamlifters. It's a modified 747 used to carry 787 fuselage parts to the plant. Just behind it you can see one of the new 747-800s in its green protective coating waiting for paint and another in the foreground, right all painted up.
We saw the 747, 777 and 787 assembly lines and the 767 line from a distance. It was a very cool tour.
