From 1:08 to 1:11 in this video you can hear a quick succession of regularly timed blasts. As the 'collapse' gets down to the level of the firefighters a succession of separate and regularly timed blasts can be distinguished.

From the Nadet Brothers film.

A protection racket is where a gang of crooks tell you bad things will happen if you don't let them look after you, where it is the crooks themselves who do the bad things. That is exactly how the Bush Cartel is controlling America, with it's staged terror attacks, scaremongering and phony war on terror.

The naming of it "9/11" so soon after always seemed to me like they wanted people to forget about it. It doesn't say anything to remind us of the incredible events and tragedies, it describes what day they happened on. "9/11", like it was just another date on the calender. Maybe they should have called it simply "Tuesday" or, more genuinely, that 'Dark Tuesday'.

We don't call the battle of the Somme "6/5"
We don't call the holocaust "3/30"
We don't call the Mount St Helens eruption "5/25"

So why the eagerness to keep the Twin Towers collapse vague in people's memory?

A-10 Warthog/Thunderbolt was flying very low over the crash site at exactly the moment the explosion, fireball occurred.

Susan Mcelwain - who lives two miles from the site, knows what she saw - the white plane rocketed directly over her head. "It came right over me, I reckon just 40 or 50ft above my mini-van," she recalled. "It was so low I ducked instinctively. It was traveling real fast, but hardly made any sound. "Then it disappeared behind some trees. A few seconds later I heard this great explosion and saw this fireball rise up over the trees, so I figured the jet had crashed. The ground really shook. So I dialed 911 and told them what happened. "I'd heard nothing about the other attacks and it was only when I got home and saw the TV that I realized it wasn't the white jet, but Flight 93. I didn't think much more about it until the authorities started to say there had been no other plane. The plane I saw was heading right to the point where Flight 93 crashed and must have been there at the very moment it came down.
