Here we have the Thunderbirds aircraft all lined up. They use six F-16 jets in their show. One neat detail which I would zoom in on for you if I wasn't too lazy, is the blackened tip of the middle jet's tail. It gets that way from sticking up directly into the exhaust trail of the lead jet right in front of it in formation. That's some seriously close flying.
The Snowbirds fly nine small, underpowered Tutor jets in their show, and bring a few extras along as well (there is usually yet another marked up as Snowbird 12) because unlike all the American teams, the Snowbirds don't get a support aircraft to haul all their personnel and gear around. They take only what they can pack into their Tutor jets.
Here we see some nice formation flying from the Snowbirds. The truck at the bottom looks like a Purolator van but was in fact a SWAT team van. (There's an armoured car right next to it.) Police were very evident at the air show but security wasn't that tight -- we were not at all searched on the way in the gate, even though we had a backpack and a suspicious electronic device (a scanner, for listening to the teams' radios).
