back again. well, I quoted the physics prof who worked it out - so if thats what was said, thats it then. That's not a lot of 'volume' of material for people to cart into a place, given the heavy weight of munitions themselves inherently. So we're talking probably the equiv of two or maybe three back-of-bakkie loads worth of actual quantity of materials. Its only civilians who need tons of fertiliser and other huge quantity methods for making things go boom.
The London bombings for instance, I think it was mentioned that they were military-grade munitions (which has never been explored) - point being, looking at the material damage done from what was easily carried on someone's back, which I'd imagine wasn't more than say 20 - 30 pounds or so, 3000 pounds of serious munitions placed correctly, would be probably quite ample.
EDIT - re WTC 'closed for maintenance' - nope, you misunderstand - the building as such wasnt ever closed down. Explosive sniffing dogs were pulled off briefly, there was some kind of 'security stand down' overall, power was turned off on a number of occasions, causing irritation to various companies on different floors, and the maintenance happened on a couple of very specific floors - all ahead of 911. Again, there's no requirement that every little thing had to have happened immediately ahead of 911, various parts could be in place for months if not years.
Also, re the box cutters story - that still doesnt explain how multiple aircraft in the air, at pretty much exactly the same time, had their transponders turned off, and also doesnt explain how supposed hijackers (I think 6 or more of whom are actually alive and rather angry at being listed as being the 911 hijackers) all managed to get into cockpits and stop the pilots from punching a 'we are being hijacked' code into their keyboards. Then there's all those cellphone calls, which technically couldn't really have been made at that time (various phone companies have only recently announced the 'new' facility allowing for cell calls to be made from airplanes, yet on 911, there was 'magic' in the air allowing scientifically impossible calls to be made without problems from apparent victims..)
But back to the current Charlie Sheen thing, where he quite accurately points to WTC 7 as being indicative of something bogus on 911 - here's the CNN piece:

(and keeping in mind the subsequent poll with over 50 000 people participating, and 83% agreeing with Sheen..)
