Passenger jet had to abort takeoff to avoid runway collision at New York's LaGuardia Airport

Federal officials are investigating why two planes got dangerously close on a runway at New York's LaGuardia Airport earlier this month despite the airport being equipped with an advanced surface radar system that's designed to help prevent such close calls. Both the Federal Aviation Administration and the National Transportation Safety Board said Monday that they are investigating the May 6 incident when a Republic Airways jet had to abort takeoff because a United Airlines plane was still taxiing across the runway.
