Everett is a busy production facility. 787s are being built at a fair rate while 777 production continues, albeit at a reducing pace. There are some 747s and 767s coming out as well. The flightline for their testing is consequently rather full. I figured a panorama was a good idea but they are hard to put on the blog without making them too small. Time for zoomify again. You can pan around and zoom in to see what was on the line this day.
