Investigation deepens into deadly runway collision

The investigation into the horrific runway collision at LaGuardia Airport entered its third day. While the airport has officially resumed most operations, Runway 4—where an Air Canada Express jet struck a Port Authority fire truck Sunday night—remains a closed investigation site as federal teams work to clear debris and reconstruct the final seconds of the disaster. The collision claimed the lives of both pilots on Flight 8646: Captain Antoine Forest and First Officer Mackenzie Gunther. Both were remembered by colleagues as dedicated young aviators at the start of promising careers.
