Yes, but kinda.
You cant tell me that if you took apart all the steel girders, concrete blocks etc, dropped all if it from a big plane in the sky, then compared it to the same collapse of the WTC that they'd fall at exactly the same speed/time?
I can understand the collapse building up momentum, getting quicker, but compared to having no friction what so ever (Free fall) there would be a noticable time difference.
WT7 fell at approx the same speed as Free fall, this has been proven by experts, demolition experts, due to the fact it had everything blown up, floors blown away, end result less friction, so it fell in about 10 seconds.
But yet the twin towers fell the same way?
My own perspective is that if something is weakened, it will lean/collapse on that side... surely?
Like when a lumber chops away at a tree, it just cant take any more and falls on its weakest point? not straight down

what are you talking about? i have seen it a million times myself on TV, it gathers momentum until there is nothing left, end of.

Freefall,
If I dropped a brick and a car from a plane at 30,000 feet or whatever... they'd hit the ground the same time

Indeed, but if i placed 100 levels of concrete inbetween the car and the ground, would the car still arive at the same time?
c'mon! its common sence!

what are you trying to say exactly? that the WTC could dodge bullets?

no, that there is bloody solid concrete floors inbetween the top and the floor!
yet you saying if the stuff was dropped from a plane at the same height it would reach the ground at the same time?
Im sure even a small child would realise thats not the case?
Floors = friction
Friction = slow the collapse down (i.e not free fall speed)

If Kyle reallly does know physics, im sure he would agree with me that the floors would be added friction, admittedly not a huge amount, but enough to make a time difference between the collapse and a free fall object

FFS READ WHAT I WROTE BEFORE MORON. i mentioned the idea of momentum and exponential increases in acceleration as each floor collapses. what do you say to that?

where have i said that the building entered a freefall

yes you are correct. this is obvious.

i still say that the floors are friction?
FFS you idiot!
Answer this..
do you really believe that the collapse would be at the same speed as free fall?
i need a laugh

Thank you, this is all i was trying to point out.
Yes momentum etc would build up, even beinging to speed up the collapse, but still not enough for it to be the same as free fall.
Im glad we can agree.

of course not, since the object is collapsing upon itself, but the collapse was an ordinary collapse in that it gained momentum very quickly indeed. nothing suspicious about the way it collapsed

I dont, personally, i beg to differ.
It just seemed too quick to me. It fell exactly the same way/speed as WT7 which was demolished.
But thats just my opinion

sorry for pointing out the obvious, but how many 100 storey buildings have you witnessed collapsing in this way?

No it wouldn't.
Unless your plane is flying in a vacuum.

Only 3.
The rest never fell down

my point exaxtly. who are we to judge the physics and measurements involved when such a huge mass is collapsing. its a whole new ballgame when we start approaching millions of tonnes of swaying steel and concrete
