Not this pish again, it's been proven that the buildings were brought down by controlled demolition, note the word "proven". The only people who don't believe it these days are either ignorant, stupid or have a degree of complicity with the acts.
Well where is this so called proof? As does it "prove" that the gravity acted differently during the collaspe of the towers?
Look, it's simple. Do what I had to do, investigate, dig and do what you need to do to find out the TRUTH. I spent 3 months purely studying about metals, explosions, aviation fuel and came up with the ONLY logical conclusion! You are on the Internet FFS, use it!!
Unfortunately the internet is not a controlled source of information and anyone can add anything to it (and probably do). I am not denying any conspiracy , of if the US government was involved but it was not a controlled explosion.
And i suppose you will also tell us that WTC7 collapsed through empathy for the Twin Towers. Think man, think.
Am I deynying that... no But if it was a controlled explosion the top of the building would accelerate towards the ground at 9.81m/s/s (the defination of free fall). The best estimates I have seen are that the towers took 10 - 15 seconds to fall. Even at the lowest estimate that is too slow to be a free fall
But there are reports of CIA men planting helium baloons in the top of the buildings prior to the controlled explosions, so as to make the buildings lighter and therefore they fell more slowly.
