The delayed United Airlines flight took off from Newark International Airport, New Jersey, at 8.42am and was taken over by al-Qaida terrorists just 46 minutes into the journey.
But – unlike the three other hijacked crafts – the plane never reached its intended target of the US Capitol Building after desperate passengers tried to stop the attackers.
They banded together in an attempt to prevent disaster after panicked friends and family told them in heartbreaking phone calls that the Twin Towers had been hit in suicide missions just moments before.
The black box, which records in-flight data, was later recovered from the wreckage after the plane crashed into a field in Pennsylvania at 10.06am when passengers tried to rush the cockpit.
In the background, a struggle can be heard, which was deemed to be the seriously injured pilot Jason Dahl trying to grab the controls.
One of the hijackers – named as Ziad Jarrah – then starts praying in Arabic, saying: “In the name of Allah, the most merciful, the most compassionate.”
At 9.57am, Jarrah became aware that the passengers are planning to storm the cockpit and prevent his suicide mission.
He is heard asking about the commotion in the back of the aircraft, asking fellow hijacker Saeed al-Ghamdi: “Is there something? A fight? Yeah?”
A minute later, he was recorded saying: “They want to get in here. Hold, hold from the inside. Hold from the inside. Hold.”
