Wow, what a shot. Love the angle of the formation, and great composition. The smoke trails are superb, this one is much less noisy. Great rendering, AmandaCatIt's not what you look at that matters, it's what you see ~ Henry David Thoreau

Does anybody know what makes the smoke? I suppose it's not a dry ice machine in the jets.
Underneath the jets there are two fuel pods (tanks) which contain diesel fuel. There is a tube from each tank to the exhaust at the back of the engine. The pilot squeezes a trigger on the control stick which starts the flow of diesel from the tank to the engine exhaust. When the diesel fuel enters the exhaust, it immediately vaporizes and creates a white smoke trail. To stop the flow of diesel fuel, the pilot squeezes the trigger one more time. This smoke trail dissipates before it reaches the ground and is considered harmless.
Luckily, I paid attention at the airshow. My Gallery
