I went to the Abbotsford Airshow in Canada in 1986. There was a World’s Fair going on in Vancouver that summer, about 50 miles away, which probably helped them get some of the other national teams. There were the Snowbirds, Blue Angels, Patrouille de France, Frecce Tricolori (Italy), and Esquadrilha da Fumaça (Brazil). That was a hell of a weekend.
I would see the Thunderbirds only because I’ve seen the Blue Angels, but honestly any military aerobatic team from anywhere would draw me just to see the best pilots in the world doing what they do best in dramatic fashion.
