11/09/01 - Attaque en direct

(Skynews) -- Extraordinary new video footage has been revealed of the shock and confusion of New Yorkers witnessing the planes crash into the Twin Towers on 9/11.

The collection of previously unseen user generated content reveals some astonishing real-life stories that came out of the terror attacks.

One of the personal accounts is recorded by a student who shares a room with a friend on the More.. 32nd floor of a building, eight blocks from the World Trade Centre.

Completely bewildered by the black smoke billowing from the North Tower on the clear, sunny day, one of the students describes the scene as "unbelievable".

"It woke us up, it's like an explosion," she adds.

Their confusion soon turns into panic when they see "objects" plummeting from the tower windows.

Audible in the background is a news reporter on the TV announcing that a plane has crashed into the iconic skyscraper tower.

Moments later a second plane slams into the South Tower and suddenly there is the awful realisation that America is under attack.

"Oh my God, it's terrorists," screams one of the students.

The horror of the attack leads to more screaming before the same woman says: "I'm so scared, I'm leaving."

The pair are then seen leaving their room in a hurry and joining a lift full of people trying to escape the building.

Equally as shocking are real 911 calls played out over desperate images of those trapped in the towers above where the planes hit.

The emergency eervices tell those in peril to stay where they are and wait for help as firefighters race into the buildings and battle their way up the towers to tackle the flames.

The material is featured in a documentary produced by the History Channel called 102 Minutes That Changed America.

It gets its first British broadcast on the History Channel on Monday, March 23, at 9pm
