【监控视频：昨晚加拿大航空AC8646航班与港务局消防车相撞的瞬间】
以下是监控录像，记录了昨晚加拿大航空快运AC8646航班（一架庞巴迪CRJ-900飞机）在拉瓜迪亚机场与港务局消防车相撞的瞬间。

昨晚（2026年3月22日，星期日）在拉瓜迪亚机场（LGA）发生的这起碰撞事故是一起重大悲剧，涉及加拿大航空快运航班和机场消防车。

以下是根据最新报道整理的事件概要：

事件详情

航班信息：加拿大航空快运8646航班（由Jazz Aviation运营），一架庞巴迪CRJ-900飞机，从蒙特利尔飞抵拉瓜迪亚机场，机上载有72名乘客和4名机组人员。

碰撞过程：美国东部时间晚上11点40分左右，飞机在4号跑道降落时，高速（估计时速约100英里）撞上了港务局的飞机救援和消防（ARFF）车辆。

消防车的任务：据报道，这辆消防车当时正穿越跑道，准备前往处理另一起与美联航航班有关的轻微紧急情况，该航班报告机舱内有“异味”。

伤亡情况

死亡：加拿大航空公司的飞行员和副驾驶在碰撞中丧生。他们都是加拿大公民。

受伤情况：至少41人被送往医院，其中包括39名乘客/机组人员和两名消防车上的消防员。虽然大多数人已经出院，但一些人受了重伤，包括骨折和一例脑出血。

调查与空管录音

美国国家运输安全委员会（NTSB）已找到“黑匣子”，并正在主导调查。关键证据包括空中交通管制（ATC）录音：

录音显示存在通信故障。可以听到一名管制员允许“1号消防车”穿越跑道，然后意识到正在降落的飞机在那里，于是疯狂地喊道：“停下，1号消防车！停下，停下，停下！”

在随后的录音中，可以听到一名控制人员说“我搞砸了”，这表明他可能因为分心或在处理两起同时发生的事件时出现了失误。

Here’s CCTV footage capturing the exact moment Air Canada Express Flight AC8646, a Bombardier CRJ-900, collided with a Port Authority fire truck at LaGuardia Airport last night.

The collision at LaGuardia Airport (LGA) last night, Sunday, March 22, 2026, was a major tragedy involving an Air Canada Express flight and an airport fire truck.

Here is a summary of the incident based on the latest reports:

The Incident
Flight Details: Air Canada Express Flight 8646 (operated by Jazz Aviation), a Bombardier CRJ-900, was arriving from Montreal with 72 passengers and 4 crew members on board.

The Collision: At approximately 11:40 p.m. ET, the aircraft was landing on Runway 4 when it struck a Port Authority Aircraft Rescue and Firefighting (ARFF) vehicle at high speed (estimated around 100 mph).

The Firetruck's Mission: The fire truck was reportedly crossing the runway to respond to a separate, minor emergency involving a United Airlines flight that had reported an "odor" in the cabin.

Casualties and Injuries
Fatalities: Both the pilot and co-pilot of the Air Canada jet were killed in the collision. They were both Canadian nationals.

Injuries: At least 41 people were hospitalized, including 39 passengers/crew and two firefighters from the truck. While most have been released, some suffered serious injuries, including broken bones and one reported brain bleed.

Investigation & ATC Audio
The National Transportation Safety Board (NTSB) has recovered the "black boxes" and is leading the investigation. Key evidence includes Air Traffic Control (ATC) recordings:

The recordings suggest a communication failure. A controller is heard clearing "Truck 1" to cross the runway, then realizing the landing plane was there and frantically yelling, "Stop, Truck 1! Stop, stop, stop!"

In later audio, a controller is heard saying, "I messed up," suggesting potential distraction or a mistake in managing the two simultaneous incidents. http://t.cn/AXfQWJiC
