Canadair RegionalJet CRJ-900

After landing on runway 04 at New York-LaGuardia Airport at night, the crew initiated the braking procedure when, at a speed of 114 knots, the airplane collided with a Port Authority Aircraft Rescue and Firefighting vehicle which was responding to a separate incident. The truck n°35 had preliminarily been cleared and was responding to a nearby flight (United Boeing 737 MAX 8 flight 2384) that requested assistance for an unknown odor in the cockpit. It entered the runway from the left side of the airplane's track, from taxiway D, when the collision occurred while the speed of the airplane was still at 114 knots. Following the collision, the airplane went out of control, veered off runway to the right and came to rest in a parallel taxiway with the cockpit and the front section totally destroyed. Both pilots were killed and nine passengers were injured. 41 passengers and crew were transported to the hospital and 32 of those have since been released. Additionally, two crew of the fire truck were injured.
Crew:
Antoine Forest, pilot,
Mackenzie Gunther, copilot.

The airplane departed Minneapolis-Saint Paul Airport Runway 30R at 1147LT on a schedule service (flight DL4819) to Toronto, carrying 76 passengers and a crew of four. After departure, the airplane continued to the southeast and reached this assigned altitude of 29,000 feet before starting the descent to Toronto. The approach was performed in marginal weather conditions with wind from 270 at 28 knots, gusting 35 knots, a 6 miles surface visibility and blowing snow. Upon touchdown, the airplane went out of control, lost its empennage, both wings and both main landing gear before coming to rest upside down. All 80 occupants were rescued, among them 8 were injured, 3 seriously. First CRJ-900 destroyed in an accident.
