Tragic audio reveals final moments of medical jet before it crashed 30 seconds after takeoff as girl & mum feared dead

TRAGIC audio has revealed the final moments of the medical jet that crashed in Philadelphia just 30 seconds after takeoff.

Six people are now feared dead, including a girl who had just been through surgery and her mum.

Pilots talk to the control tower at Philadelphia Northeastern airport in what appeared to be a conventional takeoff just after 6pm on Friday.

But disaster struck just 30 seconds into the flight, when the plane crashed into a busy street in Philadelphia.

At first, the control tower relays information with the pilots, directing the flight through airspace.

The doomed pilot’s final words to the tower are “one, two, three point eight, mike tango sierra, zero, five six, medivac, thank you. Have a good day.”

An air controller then repeatedly tries to get in touch with the plane.

They say: “Medivac, medservice, northeast tower, are you on frequency?”

“How do you hear this transmission?”

But, soon after, the controllers realise something has gone horribly wrong.

“We have a lost aircraft, we are not exactly sure what has happened so we’re still trying to figure it out for now.

“The field is going to be closed, so no in-bounds or out-bounds probably.”

Horrifying footage of the crash was caught on dashcam and doorbell cameras after the jet careened into the ground.

It is not yet clear what the cause of the crash was, but an investigation has already begun into the Learjet 55 disaster.

A bright orange fireball erupts into the sky and lights up the night following the deadly impact.

The plane was flying from Philadelphia to Tijuana and was set to make a pit stop in Missouri.

The child had received “life-saving treatment” and was heading home to Mexico, the New York Post reported.

Everyone on board the flight was Mexican – but their identities are yet to be released.

It is not yet clear how many people are dead, but six people on the ground were treated for injuries at hospital.

Jet Rescue Air Ambulance, which operated the flight, said four other people including a doctor were also in the aircraft when it crashed.

The company said in a statement: “We cannot confirm any survivors.

“Our immediate concern is for the patients family, our personnel, their families and other victims that may have been hurt on the ground.”
