State police in Ohio say an out-of-control car "disintegrated" when it went airborne and smashed into a highway overpass pillar.

The 19-year-old driver was in critical condition.

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 and then flying through 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 afterward.

Investigators are trying to determine how fast the car was going.
