I'm going for a week as a volunteer tarmac marshall, this will be my 8th airshow. It's a great flying fix and being on the tarmac you get meet the overseas pilots and see lots of extra stuff. One year I got into the cockpit of a B1B. Take an airband radio, it adds another dimension to the experience.
Saturday and Sunday look to have more action. The night display sounds exciting, but just seems to be a few parachutes, a glider and a flare drop from a Herc. Is it really worth the effort to make Friday night over either of the other days? I'm guessing Sunday is usually the busiest in terms of crowd numbers?
The best part of Friday night is seeing and hearing Connie take off at night. You will get more bang for your display buck in the daytime, the Saturday Sunday daytime crowds can be overwhelming. Sunday is usually busier than Saturday but the weather can change that. If you can get a trade pass for a trade day, do so. Looking forward to the F22 display.
