Chilling air traffic control audio reveals utter panic in the cockpit of a private jet moments before it crashed in a fireball on a Florida highway, killing two, as the pilot's last words emerge

Disturbing audio from air traffic control has revealed a moment of utter panic on a private jet moments before it crashed on a Florida highway, killing two people.

The sound captured on board the Bombardier Challenger 60 aircraft appears to be a sound of panicked voices or a malfunctioning aircraft, but it is impossible to say.

This was the last transmission from the plane, which had five people on board, before it crashed on I-75 outside Naples Friday afternoon at 3:15 p.m.

Three people survived the tragedy, although details about whether they were injured have not been shared.

None of those on board have been identified and a cause has yet to be determined, although one expert suggested the loss of both engines could have been caused by a bird strike.

The plane was one minute away from making an emergency landing at Naples airport, but another audio moment shows how the pilot already knew they wouldn't make it.

“Okay, Challenger, Hop-A-Jet 823, lost both engines, emergency. I'm making an emergency landing,' the pilot said.

Air traffic control told colleagues that there was an emergency and informed the pilot that he could land on runway 23.

But the pilot replied: 'We can land, but we won't make it to the runway. We lost both engines.”

Painful seconds of silence pass before a moment of pure, unintelligible panic hits the pilot.

Air traffic control sends back, but it is already too late. The next transmission is another warning from the controller that an emergency was in progress.

“Everyone on standby, there's an emergency going on, everyone on standby,” she said.

Seconds later, a rescue helicopter requests permission and it is granted immediately. The plane landed just 7.5 kilometers from the airport.

Numerous aviation disasters, even involving much larger jetliners, have been caused by bird strikes, including the 'Miracle on the Hudson' US Airways Flight 1549 in 2009.

Dramatic photos and videos taken by passing motorists showed the burning wreckage and debris strewn across the highway.

One video showed an explosion rocking the burning plane, and seconds later the charred left wing fell off.

At least one brave motorist was seen rushing to the crashed plane, hoping to help the survivors despite the extreme danger.

According to data from FlightAware, the flight was en route from Ohio State University Airport to Naples Airport, although the college says the plane was only using its facilities and had no connection to the university itself.

The plane was owned by Hop-a-Jet, a Florida-based private charter company, and had no ties to the university.

The company said it had received “confirmed reports of an accident involving one of our leased aircraft near Naples” and that it would send a team to the crash site.

“Our immediate concern is for the well-being of our passengers, crew members and their families,” the report said.

The Federal Aviation Authority closed all southbound lanes for 24 hours while they investigated the accident.

One FAA investigator was already on scene and more were expected to arrive this weekend. A preliminary report should be issued within 30 days.

Police and emergency workers flooded the scene and state forces opened the northern country only four hours after the accident.
