Friction and other facors may affect the speed at which things fall. Ever drop a feather?

Randy G. you ever drop a sheet a sheet of paper?

The WTC Twin Towers was the finest demolition of all time. Credit for that masterful job was not sought for, nor will it ever be rightfully assigned.
The myth America has now become is sufficiently robust that it will carry most of the gullible to the surprise deathcamps, with very little protest or bloodshed.
To trust authority in this day of technology and deceit is suicide.
Hitler told the Jews and gypsies they were heading for better conditions, thus by their own energy and will, they went obediently to the slaughter.

speed of gravity yes, terminal velocity, no. Terminal velocity requires an extremely long distance, alot taller than the towers,(I don't know how far all I know is that it takes a long freefall to reach) I'm not even sure if a skydiver can reach terminal velocity.

yes they did fall at free fall speed. people need to consider that there is friction which accounts for the little bit of extra time. if you have any clue of physics equations or mathematics, take a look at the link the my buddy Rosey has posted. it's a great site and explains free fall speeds, terminal velocity and the energy expenditures . check it out and you'll have your answer

No they did not.
The floors below provided some resistance to the speed of the collapse. You not only have the structure but also all of the contents of those floors which was building as they collapsed.
The floors above came down onto other floors and caused the collapse of those by weight and shock. As the collapse continued the sheer weight and speed made the lower floors collapse faster. This however did not reach freefall speed.
I have reviewed my videos of these collapses and it was quite fast, which I think that the fact the buildings main support was the outer walls only that allowed for the collapse to happen in the first place.

The towers did not fall at free fall speeds. This means they did not reach terminal velocity.
According to NIST, which used seismic recorders & other techniques to measure the time, the exterior panels took 9-11 seconds. Free fall would have taken 8.5 seconds. The inner parts of WTC1&2 (roughly 60 stories of WTC 1 and 40 stories of WTC 2) stood 15 to 25 seconds after collapse initiation before they, too, began to collapse.
See Point 6 at http://wtc.nist.gov/pubs/factsheets/faqs_8_2006.htm
(read this carefully)
In summary
The outside parts of the twin towers fell almost at free fall speeds since they were unimpeded.
The inside parts took much longer, since it was impeded by the bulk of the towers.

All things fall at the speed of gravity. There is no other way.
But I don't know if they reached terminal velocity.

Would it have made a difference? Wouldn't the victims be just as dead?
