This the plane that was crossing right to left. Emerging from the smoke of the other plane after they passed each other. I was pleasantly surprised with this, because when you have the camera drive on burst, you are never quite sure what you are going to get!
@stevejacob I know, to think you used to be restricted to 24 or 36 on a wet film. This day, counting all the shots for the Pumas & the Arrows I took 531 shots - the expense!!
