Sometimes it's good to be reminded of the human side of 9/11 while getting so absorbed in the fact of its being God's judgment on the nation. This is a film I saw fairly soon after the attack, done by two French brothers who just happened to be filming a documentary about the training of firefighters when 9/11 came along. They were filming at the fire station closest to the WTC when the towers were hit and the event became the focus of the film as the firefighters were of course called to the scene.
When I first saw the film, certain noises from within the burning tower were so clearly and depressingly identified as the sound of bodies hitting the ground outside, having fallen from a great height above, I've never been the slightest bit tempted to interpret those noises as the controlled demolition explosions the "inside job" conspiracy thinkers try to make of it. But I'm watching it again so I'll see if I still agree with my first impression.
And it's very clear: They all know it's falling bodies. It starts about 35:50 on the counter.
And here's another great film about the people involved in 9/11, the very touching story of the enormous variety of boats and their captains who came to rescue people stranded at the south end of Manhattan island as the WTC burned.
