Most people don't know that there were actually 3 buildings which came

The third building, WTC 7, can be seen here

There is no mention of this building in 911 Omission Report.

Can fire make a building come crashing down at free fall speed?

If you think it can, patent the idea and make billions in the
demolitions industry!

How do we know WTC 7 was demolished?

If WTC 7 collapsed in 6 seconds, and it takes 6 seconds to free fall
from the roof of WTC 7, then you got it - WTC 7 underwent a free fall.

This means as the each floor was falling straight to the ground it did
so without crashing into anything on the way. ONLY CONTROLLED
DEMOLITION CAN ACCOMPLISH THAT!

PROPOSITION 1:
It took a total of 6 seconds for the roof of WTC 7 to reach the
ground. This proposition is supported by the empirical,

http://video.google.com/videoplay?do...32340306101329
Collapse start time: 17 seconds
Collapse end time: 23 seconds
Total collapse time: 23-17 = 6 seconds

PROPOSITION 2:
A free fall from a height equal to the roof of WTC 7 would take 6
seconds. This proposition derives trivially through (Galilean)
kinematical considerations alone:

Displacement = initial velocity * total time + 1/2 * acceleration *
total time^2

or

s = ut + 1/2at^2
where
s = 174 m (height of building)
u = 0 m/s (building was stationary prior to collapse)
a = 9.8 m/s^2 (since gravitational field strengh averages at
a constant)

Thus,
174 = 0 t + 1/2 9.8 t^2

Solving for t
t = sqrt( 2 * 174 / 9.8)
= 5.9590
~ 6 seconds

Let's assume that a demo team somehow got in the towers to rip open
insulation, cut some beams and install trip and guide wires all over the
buildings along with the explosives...and their work went unnoticed.

What do you think happens to explosives in the high heat of burning jet
fuel? Do you think they calmly wait for the computerized sequence to send
signals through the trip wires? Oops, the trip wires are melted and the
explosives start to go off out of sequence because of the heat, which would
kind of screw up the controlled demolition theory.


You only need to rig the one floor below the center of the stack. The
pancaking effect will take care of the building.

Whadaya think? Three guys and about two hours?
