This was pretty amazing. The Jet would fly by with the 2 steams of smoke coming off the back of the wings. Then several seconds later the 2 lines of white smoke would curl into smoke rings. I can’t figure out how the air would be traveling in order to turn those 2 separate lines into a series of smoke rings like that. I wish I had taken a better picture of the rings, but I felt a little silly taking pictures of smoke in the sky.
