A ground collision between an aircraft and an airport truck on a taxiway at New York's LaGuardia Airport has caused panic and chaos. Unverified social media reports indicate that the incident happened near runway 4. With the collision reports surfacing, there is apprehension that the airport may have temporarily shut down.

The flight-tracking data shows that the collision may have involved Air Canada CRJ flight AC8646, flying from Montreal, and a fire truck identified as Truck 1 while attempting to cross runway 04/22. 

The US Federal Aviation Administration issued a ground stop for all planes at the airport, according to a notice from the regulator. The FAA notice showed that the reason for the halt at the airport was an emergency and there was a high probability of an extension, without specifying any details. The regulator, in a seperate notice, said that the shut down could extend to 1800 GMT. 

Videos of the incident are surfacing on social media. The aircraft appears to have sustained significant damage in the reported collision.

Passengers were reportedly evacuated onto the tarmac. While unconfirmed reports of injuries have surfaced, some sources indicate that five firefighters sustained critical injuries and over 100 passengers were hurt. 

The audio of the air traffic control tower surfaced on social media. The ATC officials are heard yelling, "Stop, stop, stop!" in panic. 

The video visuals show that despite the stop warnings, the ground vehicle collides with the plane.
