Released audio from Air Traffic Control at LaGuardia Airport has exposed one controller admitting he “messed up.”

Said aviation hub was the scene of a fatal accident that saw two pilots lose their lives late Sunday.

An Air Canada flight was landing on the runway. At the same time, an emergency firetruck was making its way across the tarmac to assist another aircraft. The miscue resulted in a collision that left two dead and multiple hospitalized.

One of the pilots has been identified.

A flight attendant miraculously survived after being flung several feet from the craft, only suffering a broken leg.

Audio footage from the tower has been released in which the controller is heard trying to stop the truck moments before the collision.

 “Stop, stop, stop, stop, truck 1, stop, stop, stop,” he says. “Stop, truck 1, stop!”

Audio cuts off and then comes back on. The controller then admits he messed up, and someone tells him he did the best he could.

“I got the word that we’re gonna be closed for a little while. If you want to prepare to return to the ramp, let me know,” he says.

“Yeah, we got stuff in progress that’s for that, man. That was…that wasn’t good to watch,” the other person responds.

“Yeah, I know I was here,” the controller replies. “I tried to reach out to my stuff, and we were dealing with an emergency earlier. I messed up.”

He’s then told, “No, man, you did the best you could.”

It’s been suggested that the controller in question was in charge of both air and ground traffic at the time.

“What we’ve heard from that control tape is it’s the same voice that is clearing the aircraft to land and clearing the vehicles across the runway,” former FAA vice president Michael McCormick said, per ABC. “In a normal tower scenario, it would be ground control working the surface traffic and tower control just working arrivals and departures.”

Transportation Secretary Sean Duffy said there was more than one person in the tower at the time, but would not disclose how many or what they were tasked with.
