I've seen the thunderbirds perform I think 6 times. It's always a good show.
Back in 2015 I think, they were taking off for practice where I used to work and number 6 declared an emergency with me. Turns out they ground crew didn't pull the pins from his gear, so it was a short flight for him.
I can also confirm that the control tower, at least inside the cab, is not the best place to watch an air show from. Once they get above our windows, we can't see anything! Lol
