San Francisco Explosion

There was an underground explosion in downtown San Francisco a few blocks from my office. Apparently the explosion caused a manhole cover to fly several feet into the air and spew flames out of the ground. A woman walking past the manhole cover at the time of the explosion was badly burned in her head and neck by the spewing flames. That's what I call being at the wrong place at the wrong time--what are the chances? Alas, the explosion was deemed to be electrical in nature and not an act of terrorism.
