A police cruiser's dashboard camera captured Monday morning's stunning crash on Interstate 675 near Dayton. The video shows a 1985 Pontiac Firebird passing by in the median, striking a culvert on the ground and then being launched into the air. The car slams into the overpass, turning into a shower of parts. The State Highway Patrol says driver Brennan Eden was ejected onto a highway shoulder. Troopers say he was alert and conscious after the crash. Investigators are trying to determine how fast the car was going.
