AP: Cause of deadly Comair crash probed

LEXINGTON, Ky. - Investigators probing the fiery crash of Comair Flight 5191 want to know why it tried to take off from a runway considered far too short for commercial passenger planes. All but one of the 50 people aboard died. Although Blue Grass Airport's main runway is 7,000 feet, for some reason the plane departed Sunday from the 3,500-foot general aviation runway. The twin-engine CRJ-100 would have needed 5,000 feet to fully get off the ground, aviation experts said.
