On Thursday, new amateur footage of the September 11 attacks on the World Trade Center in New York City was released by the National September 11 Memorial & Museum.

The museum released the footage as part of the launch of a new Web site that aims to bring together images and stories from the day.

Dramatic Footage

It's a view of 9/11 that most have never seen.

A camera in Brooklyn pointed through a chain-link fence at black smoke pouring from one skyscraper, while a plane pierced another.

One videographer asked, "What kind of crazy person would kill themselves like that?"

Papers flew through the sky with some of them ending up in the filmmakers' hands.

That evening, September 11, 2001, another camera found firefighters trudging through dust-caked streets, carrying their helmets or a spare pair of shoes. The ruined facade of the World Trade Center is before them, the area strewn with dust and papers.

"They say that 9/11 was the most digitally documented event of all time," said Alice Greenwald, director of the planned museum. "There were vigils in Tehran, Berlin, London, Moscow, Tokyo. ... We're asking people everywhere to help us tell the story."

The foundation has acquired 500 hours of video archives assembled by Camera Planet, a private team of filmmakers who collected professional and amateur videos from the day and its aftermath.
