The Fleet Week air show in San Francisco is wrapped up by the Blue Angels.  The sneak passes made by the pair are an opportunity to try and get something interesting.  Since they display over the bay and the city is known for having high relative humidity, I am always hoping to get some good vapor shots.  This time out, that wasn’t to be.  The air seemed to be pretty dry and there was not a lot of vapor on show.  However, the fast pass from left to right takes the jet in front of the hills and Alcatraz which provides some detail to show up the distortion caused by the shock-waves.  The large number of boats and associated masts meant a clean shot was tricky but I got a couple I was pleased with.
