Was 911 controlled demolition vs. collapsing do to the jet fuel fire?

Question

I recently watched a movie on YouTube http://www.youtube.com/watch?v=7E3oIbO0AWE

giving some hard facts on this question.

Answer 1

My grandfather is a professor of metallurgy and worked for Bethlehem Steel for 27 years as production engineer and also lead their fatigue resistance team. When I asked him if ignited jet fuel could've caused the collapse of the WTC, he said "absolutely", with no hesitation. He said any metallurgist will tell you that a steel structure like that of the WTC will not start to melt unless the temp is 2600 Fahrenheit, but it will weaken enough at 1600 degrees to collapse a building that size. Jet fuel will heat steel like that to 1800.

As far as the rest of the 911 conspiracy myths, they've all been dismantled into a state of foolishness by the following article,,,,,,,

It is easier to believe in the Lochness monster than to buy into these silly 911 conspiracies myths.

Answer 2

Controlled demolition.

Is that the final cut?  The Final Cut is the Best One!

I hope that you will keep digging!  There is so much to learn about the 9/11 attacks.. that one documentary can't present it all.  Here's a few 9/11 websites that I feel are genuinely trying to find the truth!  (without going to far out in left field... "no plane" theories.)  Be careful there's a lot of disinformation out there... on both sides.  Especially the Government's 'Official Story' .  Most importantly keep in mind.  We don't have to prove anything!  The government needs to prove their theory!  And they need to open up a new unbiased Investigation.

Answer 3

Anyone who believes that the towers were demolished by us is a DOLT!

Answer 4

The collapse of the buildings was obviously and indisputably a demolition job.

Answer 5

It was collape by the plane flying into the building taking out support structures and the fire that weaken the building.
