NEW YORK (AP) — An investigation into last month's tragic collision between an Air Canada jet and a fire truck at LaGuardia Airport, which resulted in the deaths of both pilots, reveals alarming communication failures. The National Transportation Safety Board (NTSB) reported that the fire truck's crew received warnings from air traffic control, but confusion led to the accident.

On March 22, the fire truck was cleared to cross the runway just 12 seconds before Flight 8646 landed. The NTSB’s preliminary report indicates that the crash prevention system at the airport failed to alert the control tower appropriately, and crucial stop lights were operational until seconds before the collision.

Initially, the air traffic controller issued a general warning to stop without specifying who it was directed towards. Eventually, the turret operator understood that the command was meant for his vehicle, but it was too late as they were already on the runway.

Both pilots, Antoine Forest, 24, and Mackenzie Gunther, 30, tragically lost their lives, along with the two crew members in the fire truck who were injured alongside approximately forty others. Despite the chaos, a flight attendant miraculously survived after being thrown onto the tarmac during the impact.

The fire truck was leading a convoy to respond to an emergency involving a reported odor on a United Airlines flight. The night of the crash was exceptionally busy, with more than double the expected arriving and departing flights, complicating the situation for air traffic controllers as they managed multiple situations simultaneously.

The crash marked a tragic first for LaGuardia, being the first deadly incident at the airport in over three decades. Investigations will continue as officials work on implementing new safety protocols to prevent such incidents from occurring in the future.
