Revision History

An Air Canada Express CRJ-900 arriving from Montreal collided with a Port Authority fire truck on Runway 4 at LaGuardia Airport late Sunday night, killing both pilots and injuring 41 others. The fire truck had been cleared by air traffic control to cross the active runway while responding to a separate emergency involving a United Airlines flight—raising immediate questions about controller workload, staffing levels, and whether LaGuardia's surface detection systems could have prevented the tragedy.
