'Most terrifying footage of 9/11 ever taken' resurfaces ahead of 25 year anniversary

News footage from the September 11 Attacks has been called the 'most terrifying footage' taken of the attacks as it recirculates in the lead-up to the 25th anniversary.

This year will be 25 years since two hijacked planes were flown into the World Trade Center in New York City, and another into the Pentagon, resulting in the deaths of 2,977 people, not including the 19 people who carried out the attack.

As the anniversary approaches news footage shot from on the ground in Manhattan after the towers were hit has seen renewed attention on social media, with one person sharing an extract of the footage, and writing: "This maybe the most terrifying video I have seen of 9/11 in 25 years MY GOD".

The footage is of reporter Newton Jones Burkett and camera operator Marty Glembotzky, who had been reporting from around a block away from the World Trade Center after they were struck by the planes.

The pair were located at a rally point for the Fire Department of New York (FDNY), surrounded by emergency personnel who were assembling as part of the enormous rescue operations carried out that day, in which 343 firefighters with the FDNY would lose their lives.

Burkett begins giving a piece to camera explaining what is happening behind them, counting himself in before saying: "This is as close as we can get to the base of the World Trade Center, you can see the firemen assembled here, police officers, FBI agents..."

The camera pans upwards, showing the towers on fire, with Burkett saying 'and you can see the two towers', before the South Tower begins to collapse.

Still maintaining composure, Burkett continued over the roar of the collapsing tower, saying: "A huge explosion now raining debris on all of us," before his voice changed in alarm as he said: "We better get out of the way!"

They rush through a nearby door to take shelter before the camera cuts out, and when it returns the camera is filming as Glembotzky flees down the street, surrounded by civilians and emergency workers, including an ambulance blaring its siren to make way as it drives.

At one point, showing incredible courage, Glembotzky turns around and films the approaching wall of dust and debris which is barrelling down the street behind them.

Burkett can be heard shouting encouragement at Glembotzky as he runs while refusing to drop the heavy camera equipment, shouting: "Come on Glem! You can do it Glem! Keep coming Glem come on!"

The street is in utter chaos around them, with shouts and sirens blaring everywhere as people ran for their lives.

Finally, having outrun the plume of smoke and dust, Glembotzky slows to a walk, continuing to pace backwards while filming the dust cloud engulfing the entire street behind them.

They would also film the collapse of the second tower, before taking shelter in an underground car park from the dust plumes, with good reason as many people have suffered from long term health problems from their effects.

In 2021, 20 years later, the two colleagues would return to the scene together, greeting each other warmly and tearfully before recalling that day.

"Second take of the standup, as I tilted up to the building, and I remember hearing the tone of your voice changing," said Glembotzky in the NBC video.

Burkett recalled: "You learn things about yourself when you go through these things. One of the things I learned about myself was that I had this extraordinary ability to compartmentalise grief and trauma."

Glembotzky tried to explain the sheer scale of it, saying: "We've seen lots of bodies, lots of body parts, we're news people, we deal with it."

He said: "The situation was so horrific, and I had never seen something like this."
