Hi there! Thanks for the cool post - it's great to know where they all are, and where to go to see them (if I ever get to Europe!). I have one slight correction for you - the one in Seattle, Washington, USA at the Museum of Flight has been located in an adjacent parking lot converted to a display area. The picture in GE, of course, pre-dates the time the aircraft were moved there.
Here are the coordinates: 47d 31' 10.78" N 122d 17' 56.98" W
