I guess the plane explosions that knocked the debris off of the building in the first place, would not have anything to do with the downward speed eh?

Take a tennis ball, stand on top of a building, throw the ball downward. now compare that speed to a ball you simply drop. what falls faster?

Have there been measurements done to prove that the debris is actually falling at the acceleration of gravity and not slower due to air resistance?
The pieces that are visible are clearly large and flat. Windows, sheets of metal, and the like. They are tumbling as they fall, thus causing significant air resistance. You can even see some larger pieces falling at a markedly slower rate.
Just curious if anyone had any info on this.

Those objects have not reached terminal velocity in the pics you are showing.

I believe it's because the force on the debris to the left is going outwards rather than falling straight down.

Later on in the fall after the debris has reached terminal velocity i.e. free-fall speeds, the collapse is going slower.
Just another great example of the deceptive tactics used to "prove" demolition. Reminds me of the WTC 7 "squibs".
The cloud you point to is below the collapse. You can still see the side of the building further up. The part falling "faster than freefall" is actually just part of the debris cloud.
Do I really have to post that pic again?
I've realised i'm wrong here as the force of gravity is the same so they will still fall at the same rate of speed even if the force is directed outwards too. But could wind resistance be a factor?

WTC 2 correct?

i can't view .avi files.
this is the one i used, ...abc footage of collapse, zoomed in on corner
is that the same one?
anyway, the debris on the left is falling down pretty much straight.
the collapse front passes it. that means air is somehow providing more resistance than a steel skyscaper. there are some steel beams that just fell out of view, and they were going at about the same rate as the debris to the left, which has, incidentally, arched out about as far as it's going to go, and is falling pretty much plum.

Do you have better pics Billybob, that show exactly what point in the collapse those stills were taken? Or did you crop them that way to hide that they were taken near the begining of the collapse.

So let me get this straight, it starts out faster than "free-fall" and ends up like this?
So, no Bsbray, the building never reached terminal velocity as the debris that did, beat the building to the ground.
