Overview
- The Bombardier CRJ-900 operating Air Canada Express flight AC8646 from Montréal struck a Port Authority firefighting vehicle on Runway 4 shortly after landing.
- The captain and first officer died; dozens of passengers and crew were treated at hospitals with several serious injuries, and two PAPD officers sustained fractures.
- LaGuardia halted operations overnight and into Monday, with closures through early afternoon local time causing widespread delays and cancellations.
- Released tower recordings capture a controller repeatedly ordering “Truck 1, stop,” a key piece of evidence for the FAA and NTSB probes now underway.
- Preliminary data indicate the jet was moving at roughly 40–48 km/h during rollout, while the PAPD vehicle was responding to another incident elsewhere on the airfield.
