I have struggled to get shots of the Boeing chase aircraft in decent light.  Whether it is the T-33s or the T-38s, my encounters have generally been on overcast days.  Finally my luck changed and one of the T-38s came in to Paine Field for a couple of approaches on a sunny day.  It was the middle of the day so the light angles weren’t great but it was certainly a step up.  A couple of passes and then they headed to Boeing Field.
