Flames shoot into the sky after a minivan smashed into the side of a gas tanker Monday night at a Long Island gas station. The woman driving the minivan was killed, police said. The crash triggered an explosion that shook houses several blocks away and shot flames more than 100 feet in the air. Homes within 2,000 feet of the station in East Islip were evacuated while the fire raged. The residents were allowed to return home early this morning.
