They Blue Angels fly here over the SF Bay at least once a year, doing all their stunts in formation. They go way down over the southern half of the Bay to get into proper formation, then fly way up to the north end, so that on return, about in the middle near the Golden Gate Bridge, spectators on the beach at San Francisco have a relatively close view of their act. But from a hill above me, on the opposite side of the Bay, I get a much better view of the entire Bay and their total procedure. Their official photographer actually takes off after them, but must fly even faster in order to take his pictures while flying past them, in the meantime getting any background scenery aligned in the same composition. I've read an article where this was explained by then current photographer himself. He actually puts his finger on the camera shutter and starts pressing it while still seven miles behind the planes in formation, because he's going so fast that he'll be right alongside them almost instantly. The composition is viewed through a simple wire finder atop the Graphic. It baffles me; but all these pilots necessarily have incredible timing and reflexes.
