Looks like the ball caps, one red and one green, are following the guy who's follically impaired. Again, this is something I've noticed about your air show photos, Ted... you stop the action so well I can pick out details about the pilots. With this one there's also the question of the angle. Judging by the angle of sunlight and the fact that your position is almost level with these planes, either they were nearly on the tarmac when you shot this or you were up in a tower. I can't decide which. Either way a great capture. Great focus, color, composition, POV, crop, etc., etc.
If you've ever wanted to make a difference but found it hard to believe that one person could... check out the Kiva Team Caedes discussion thread and discover that anything is possible.
The other possibility is that they were banking at just the right angle to make it look like you were level to them. I know you're tall Ted, but only Paul Bunyan could have gotten that high, even with the use of a Little Giant ladder. 8P
