Nathan Watterson, 20, and Howard Pisor, 35, both of Hilliards were flown by medical helicopters to Pittsburgh hospitals following the 5:15 a.m. crash.

State Police said Watterson was driving a car north on Route 38 near Parker Road and entered the southbound lane to pass another vehicle in front of him.
