Thanks Rick!
The picture is kind of deceptive as it was after my firing pass under his tail was over. He dove a little and to the right and I pulled up and away to the left to minimize exposure. That, and the little delay in getting to the Pause button, makes it look worse - frozen in time - then it really was. A second or two later he lit up.
Gotta give the observer credit though; when I pulled along side for the flamer screenshot he still had some fight in him and fired about 5 rounds before I decided I might be too close!
