I love em. Had a couple zoomies chase each other over us today and one came back around and gave a wing waggle to our waves. Not saying where but I could see helmets from the ground. Nothing like it to to get your heart rate up. Better than coffee!
My favorite was about 12 years ago during our 4th of July show at our rural airport. Airforce from Edwards came over very low, about 300 feet before shooting off into the sky just as a 55 gallon drum of jet fuel was ignited on the ground. It was like a bombing run! What a blast (no pun intended).
I had 3 A-10 Thunderbolts fly over the me on the highway a few years back. They were definately under 1000 feet and it was an awesome sight!
