At a gas station in San Bruno, a surveillance video caught Thursday's natural gas explosion and fire on film. "You can see one man getting ready to fill up his car when something catches his attention," notes NBC Bay Area, who first aired the footage. "That something was a huge fireball caused by an explosion of a 30-inch pipe."

The woman running across the street with a kid in her arms, for lack of a better cliche, is heartbreaking.

While there's no sound on the film, "people said there was a deafening whooshing noise that reminded them of a jet engine."
