Harrowing new dash cam footage shows view of tragic Philadelphia plane crash that saw all on board killed

Horrific footage shows the view from the ground when an air ambulance crashed into a Philadelphia street on Friday (31 January).

All six people onboard the air ambulance died, while officials confirmed that someone on the ground had died as a result as well.

The plane had been carrying a Mexican girl who had spent months in hospital receiving treatment and her mother back home, while there were four others on board the plane.

Casualties had been expected, with the flight operator Jet Rescue Air Ambulance saying they 'cannot confirm any survivors' before the tragic fate of all six who were on the jet was known.

A further update from Philadelphia mayor Cherelle Parker said that the seventh victim of the crash was a person in a car.

At least 19 other people were injured in the catastrophe, with most since having been released from hospital.

With the jet crashing down in a busy area of Philadelphia, a number of buildings and vehicles were damaged in the resulting fireball caused when the plane collided with the ground.

As such, a number of devices including dash cams and doorbell cameras caught the harrowing scenes and resulting damage.

Some of the footage shows the plane plummeting to the ground just seconds after taking off from Northeast Philadelphia Airport, and other videos have been circulating on social media to show other angles and perspectives.

Another piece of footage comes from a dash cam located in a car just down the road from where the plane crashed.

In the video the plane can be seen falling to the ground before the night sky is lit up by the sizeable fireball caused by the crash, with flames and smoke climbing high from the point of impact.

Warning: contains distressing scenes

National Transportation Safety Board chair Jennifer Homendy said the disaster was a 'high impact crash' that left the plane 'highly fragmented'.

Authorities have been working to assess the damage done and gain as full a picture as possible of what happened.

Debris from the plane is being collected as part of the investigation, and a search for the cockpit voice recorder is underway in the hopes of shedding some light on the air ambulance's final moments.

Air traffic control did not receive a warning before the crash, and piecing together the course of events which caused the plane to crash is important.

Airport staff told the plane to 'turn right when departing' the airport, and then about 30 seconds later tried to get a response from the flight by asking: "You on frequency?"

Afterwards they raised the alarm, with a controller saying: "We have a lost aircraft. We’re not exactly sure what happened, so we’re trying to figure it out. For now the field is going to be closed."
