This weekend was Fleet Week in San Francisco — but, alas, the US Navy Blue Angels for the first time in many years were elsewhere. Canada’s Snowbirds were the star attraction for this year’s airshow — and, having seen them perform for the first time last year, they are pretty amazing. The Snowbirds’ formation flying — with so many aircraft — is very beautiful. But we still miss the sound and speed of our Blue’s F-18’s!
