We relocated to the other end of Boeing Field for the return of the Blue Angels. They ran in across the field trailing white smoke. Unfortunately, with little wind, this meant a pall of smoke was now hanging over the airport. As they broke into the downwind and then turned onto final, it was sometimes hard to see them at all. A healthy boosting of the contrast makes some of the shots a bit more visible but, in truth, the viz was really awful. I only hope they had a slightly better view of the ground than we had of them since their being able to see was slightly more important.
