Back in CNN’s glory days, when a big event was happening around the world, it was not uncommon for the promotional team to start recording what was happening in the newsroom as the events unfolded on the TV’s for millions of viewers.

That was the case on September 11, 2001.

The promotional team at CNN started recording the CNN newsroom about a half-hour after the plane hit the first tower.

This is raw footage from that day inside CNN.

It is powerful to watch it all unfold, not on TV, but behind the scenes in the newsroom. You even see CNN founder Ted Turner (the 24:00 mark) walking the floor of CNN Center.
