I had a couple of encounters with the same jet while it was on test. (It’s brake dust already showed up in this post.) This 787-9 is, by now, part of the Korean Air fleet. I saw it depart from Paine Field one evening in pleasant light. The low sun angle really brought out the shape of the underside of the wing in a way that normally you just don’t get to appreciate. It showed up a second time while I was out to get the farewell flight of the Delta 747 which I wrote about here. It came in at a similar time and the wet weather helped to make the pale blue color scheme pop a bit more.
