You can see just how high and hot the flames burned at times after Sunday's early morning crash. The 68-year-old driver of the tanker truck died at the scene; four other people were injured. Police believe a suspected drunk driver caused the chain-reaction on Interstate 5. The 21-year-old's Nissan crashed into a barrier in Federal Way, Washington -- just south of Seattle. That car was hit by another, which was then hit by the tanker truck. Then came a series of explosions as the truck went off the side of the road, and a tanker fully-loaded with gasoline ignited. A fire was still burning at the crash scene by Sunday afternoon.
