Four people were injured when authorities said an Air Canada passenger plane collided with a fire truck on a LaGuardia Airport runway late Sunday, according to two sources familiar with the matter.
The plane, a Jazz Aviation flight operating on behalf of Air Canada, struck a Port Authority vehicle that was responding a separate incident around 11:40 p.m., according to the Port Authority of New York and New Jersey.
The pilot and copilot on the flight are badly injured. A sergeant and an officer have broken limbs and are in stable condition at a hospital, according to preliminary information from the sources.
No other major injuries have been reported.
Port Authority described the truck as an aircraft rescue and firefighting vehicle. It was manned by police officers, the sources said.

The sources said the plane was at the end of landing and going about 30 mph when the collision occurred.
The Federal Aviation Administration said the plane was a Bombardier CRJ-900 twin-jet aircraft flown by Air Canada Express, also known as Jazz Aviation, from Montreal.
The accident happened on LaGuardia’s Runway 4, it said. The FAA said it was investigating the crash.
Jazz Aviation said 72 passengers and four crew were on board Flight 8646, but said the numbers were based on the preliminary passenger list.
Video posted on social media a passenger jet on the runway with its cockpit high and the underside of its forward fuselage mangled.
The airport was closed and flights were subject to a ground stop because of an aircraft emergency, according to the FAA.
The National Transportation Safety Board said it is launching a go team to investigate the collision.
LaGuardia is in New York City's Queens borough.
