I've heard accusations that the building was intentionally brought down but no evidence besides the fact that it fell straight down.
There is video clearly showing the puffs of sequenced explosions on successive stories, just like every Las Vegas demo you've ever seen - plus the owner's admission
Do you have a link to that admission by chance?
I have a quote:
9/11 – My own review of the entire event.
by Joël v.d. Reijden
Apparently Larry Silverstein tries to explain something to us in the 2002 PBS documentary ‘America Rebuilds’:
“I remember getting a call from the, uh, fire department commander, telling me that they were not sure they were gonna be able to contain the fire, and I said, "You know, we've had such terrible loss of life, maybe the smartest thing to do is, is pull it. And they made that decision to pull and then we watched the building collapse.”
Some contende that "pull" means to deliberately demolish - others argue otherwise. Some argue that video shows a controlled implosion of WTC7 - judge for yourself here:
WTC7 going down
Does he mention the reason he knocked down his own building, or how he knew there would be such a golden oppertunity to do so?
See above - IF "Pull" means to deliberately bring down, it would imply that:
1. Large buildings are pre-wired so that they can be imploded if collapse is emminent.
2. WTC 1 & 2 MIGHT have been deliberately brought down, rather than risk having them collapse into other, unaffected buildings, (boy, I would hate to have to make that decision...)
3. For obvious reasons, they don't want the fact that these buildings are "pre-demo'ed" to get out.
The impications either way are staggering - after the first attempt on the WTC, either:
we did nothing, and if something bad happens, we are gonna watch helpless and "let 'er drop", or...
We pre-placed explosives and control circiutry, so that if a building was reasonably beleived to be in imminent danger of collapse after another terroist attack or similar disaster, a controled implosion inside it's footprint could be assured - but then someone has to make that call....
