NEW YORK (PulseWire) — Following a fatal collision between an Air Canada plane and a fire truck at LaGuardia Airport, the airline confirmed that all but four of the injured passengers have been released from the hospital. The crash occurred on Sunday and claimed the lives of two pilots, triggering ongoing investigations into the incident. Approximately 40 individuals sought medical treatment for various injuries, some of which were serious. Details on the four individuals still hospitalized are not yet available.

The Air Canada flight, originating from Montreal and carrying 76 people including crew, collided with the truck that had been cleared to cross the runway just moments earlier. Crews have been actively removing the wreckage from the tarmac to re-open one of the airport's two runways, which had been blocked since the crash.

On Wednesday afternoon, airport workers began towing away parts of the mangled aircraft while righting the overturned fire truck that had been laying on its side since the incident. Air Canada stated that the aircraft would be moved to a hangar, where efforts to reunite passengers with their belongings would commence.

As the investigation unfolds, many onboard credited the pilots' quick reactions for preventing further casualties, as they managed to stop the plane just before the collision, allowing many to escape, including a flight attendant who was ejected from her seat but survived. The two pilots were identified as Mackenzie Gunther and Antoine Forest. The two firefighters in the truck sustained injuries but survived.

The tragic event has sparked discussions around safety regulations at busy airports and the importance of communication between air traffic controllers and ground crews.
