Impressive!
As to the patterns they "drew" into the sky, I like 3 and 4 best, though I am also fascinated by the clarity of the first, where I can see all the pilots. It must have been a wonderful day. The sky was just perfect for this airshow!
Great shots. My father and I have managed to catch them when they have done their North American tours over the past 30 years. They came once with the Gnats and once with the Hawks. Great team and great photos.
