‘Stop, stop, stop’ heard from control tower during LaGuardia Airport collision

In audio recorded Sunday night, a voice could be heard telling a vehicle multiple times to 'stop,' before a regional jet struck a fire truck on a runway while landing at New York's LaGuardia Airport. The pilot and co-pilot were killed in the collision, which crushed the nose of the aircraft, while 39 passengers and crew members were taken to area hospitals, some with serious injuries.
