it's the rush of oxygen rich air being pushed/forced out by the explosions occuring in WTC2. The air acts as fuel for the fire in WTC1, causing it to flare up.

Just my hypothesis.

Chris, why are there explosions in WTC2? are they the natural consequence of a plane hitting the building?

Did WTC7 collapse because of explosions from air pulled in from a block and a half away?

in my opinion it reminds me of when you force air into a dying campfire...there was obviously an overwhelming force of air rushing all about the collapse which can "breath life" back into a seemingly dead fire remnant.

Just for your information:

Air is mostly nitrogen, and about a quarter oxygen or so. For the purposes of describing a combustion reaction you'd describe it as (O2 + 3.76N2) ...

That's for all you nerds :P

The audio has clearly been replaced with a recording from a conventional demolition.

But it also begs the question, which (if either) is the original?

If the clip with the claimed altered sound is from the BBC, I'm left to wonder what overdubbing a CD sequence would do for them? How could it possibly help the official story?

Do we know who shot this video? Although not a guarantee of honesty, they ought to know what it sounded like!

In the quicktime you posted.

thanks for the post...anyone notice the immense amount of white smoke at the BASE of the tower prior to collapse (almost at the point where the camerman runs away...)

good stuff..

Anyone know the ORIGINAL source?

There was little or no exceleration due to gravity demonstrated during the fall of the towers! This is impossible if the towers had collapsed according to the "official story."

Dr. Steven Jones is absolutely correct. The towers did not fall in a gravitational collapse alone. They were brought down with incendiaries & explosives!

"acceleration"

The is a simple illustration of why the collapse times can be used to pry open peoples minds to the absurdity that is the OCT:

Quarter mile = 1320 feet

WTC1 = 1368 feet

WTC2 = 1362 feet

According to the OCT the top floor of each tower fell THROUGH hundreds of feet of Structural steel and concrete faster than ->

Immediately the muted idling rumble from the V-12 opens up fully and emits a snarl that grows to a higher-pitched thumping note. The prancing horse gulps in as much air as possible and turns all those air molecules into 650 bhp and 485 lb.-ft. of torque. The rear tires spin momentarily, and fight to bite into the asphalt. Easy and smooth on the throttle here because too much wheelspin slows the car down and loses precious time on the clock. Just before the first shift at 44 mph, get to full throttle. In Race Mode, the F1 transmission will swap gears in as little as 150 milliseconds.

Zero to 60 mph: 3.3 seconds.

Quarter-mile run: 11.1 sec. at 133.0 mph.

Unbelievable.

The Enzo has just recorded the best Road & Track acceleration run ever for a road car. Its 0-60-mph run equals the fastest time logged just a month ago by the all-American Saleen S7. And its quarter-mile time and speed pulverize the mighty McLaren F1's numbers of 11.6 sec. traveling at a mere 125 mph past the quarter-mile mark. Wow!

towers fall at a relatively constant velocity? They should've started very slowly & accelerated greatly near the end?

All sorts of elementary physics were violated in the "official story."

The pancake collapse, in addition to requiring over 30 seconds to occur, also leaves the core columns standing.

It took a few seconds longer than that:
