The building is already on the ground. All that is necessary to classify a 'collapse' is that the structures which make up the building aren't in their original form. All an explosion would do is to create a large shockwave through the building, just like collapsing floors would. It wouldn't pull it to the ground.

You know I meant the top of the building.
The physical structure changes but the floors still fall, and the floors would still meet more resistance than that provided by air on the way down. The shockwaves would contribute to this and may cause floors to disintegrate, but I doubt a natural fall, even in these circumstances, would be as rapid.

it wasn't a natural fall, a fecking great aircraft had hit and the building had been on fire for quite a while

"even in these circumstances" = even a big fat plane smash, fuel, fire, weakened (not melted) steel, any tensioned cables, ad nauseum.

You are failing to see one small point though. The tower did not fall in 6.odd seconds or whatever you said, it fell in a couple of hours and 6.odd seconds. It started falling as soon as the aircraft hit it. The structure held for ages, but once it gave way, it gave way spectacularly quickly, but given its construction it was no quicker than expected.

Newton's Law still applies. It does not matter how heavy an object is, it will not increase the speed and acceleration of gravity. The failure of each floor structure no matter how week would have significantly slowed down the collapse.

[Buffoon]

Each and every day we get evidence that governments here and in the US are totally incompetent. On that basis, is it even remotely possible that that any government would have the wit to pull this off?

[Spacecadet]

even so I don't think there was anything suspicious about how long it took to collapse, the mass of the building is large enough to almost negate any resistance due to atmosphere and considering it took about 15% longer to fall than if it had been under free fall I'm happy that it was not quickened by any other forces.

Every single expert who I have seen interviewed backs up the government in why they collapsed and they have a mountain of evidence to go with it.

All theories to the contrary come from crackpot amateurs with feck all evidence to back them up. Its all based on poor science and speculation.

I watched that documentary on Sunday and the kid behind the loose change film had the audacity to dismiss the popular engineering magazine counter arguments on the basis that they weren't qualified. Work that one out???

where's the "significantly" from? it would have had an effect, but given the momentum of the floors above smashing down then it would have been negligible

The fire was across maybe 10 percent of the structure. The lower floors may have been weakened but it's still not plausible that a building of that size and with that much steel, concrete etc would fall neatly into it's basement at almost the same speed as free-fall unless every floor gave way symmetrically at regular intervals providing the upper floors with no resistance whatsoever.

[Jawz]

My understanding was that the steel, supporting the building had been weakend significantly by the initial crash and then further by the heat from the subsequent fire so when the top floors collapsed it didn't have the strength to prevent other floors from collapsing
