While spending a month in Hemet, CA, I attended the their Air Show. They had a team of retired Air Force pilots demonstrating formations.
Aerial acrobatics
Lots of Fly-bys with various aircraft
There were NO Blue Angels, but they did have an A-10 Thunderbolt that flew in from Tucson put on an extensive demonstration of the plane's maneuverability.
On the A-10's last fly-by, a P-38 went up to join with the A-10.
The thing that I found most impressive was a 26-year-old lady that put her aerobatic plane thought some tough maneuvers. Not only could she fly her $300,000 plane that had over 600 Hp upside down in a straight line . . .
