At this moment, The Navy's Blue Angels are flying over San Francisco, practicing for an upcoming air show. It happens every year at this time. Every year the Navy blandly assures us that the pilots stay well above the minimum altitude. Three years ago I saw a pilots head through the canopy as he flew over a supermarket parking lot. Fifteen minutes ago, two planes were low enough for me to see the shape of the letters on the side and the lines of the canopy bracing struts. I suspect the Navy of telling lies. Some day one of them will crash. It happens. It's happened before. And decades of citizen complaints will probably be swept under the rug. It's a couple of years since I saw the number; I think the minimum altitude is 700 feet, which seems a little low for comfort.

End of rant.
