Boeing seems to have addressed a lot of the problems with the KC-46 Pegasus program (but not all of them yet) and so the Air Force is taking delivery of jets at a regular rate. Since plenty have been built, there are enough to deliver. I was at Paine Field a while back when one of the jets was heading out on a test flight. I ended up being there for both the departure and the arrival since the flight was not that long. The good summer light that Seattle gets but we don’t like people to know about meant I got some reasonable shots of it.
