I watched about half the video and I stopped because i could not believe peoples could actually think the movie was in any way of form scientifically based. Did anybody watch the programs on tv where they show the demolition of buildings? It takes weeks to prepare a controlled demolition and we are not talking about only the planning because the explosives have to be installed and that takes lots of time.
If the buildings were demolished by bombs, why would the peoples planting the explosives bother to make a perfect controlled demolition where all would go down in a straight line? That does not make any sense because it was useless to do so and it was easier to simply blow it up any way they could. This is not like they were trying to minimize the damages after all.
For the twin towers the conspiracy theory also implicate the bombers would have to climb to the exact location the planes hit to plant the bombs, with the people going down and with the damages. This was impossible.
One guy say it was impossible for the temperature to reach a high enough level to melt steel. Again that is bullshit because even a house fire is subject to the convection effect that make the air rise and get hotter and hotter the higher it goes. That is the principle behind flash-over where entire room with no apparent high temperature combustible inside just turn into a super hot ball of flames. Wood burns at a way lower temperature than fuel and a house will flash-over with temperatures of way over 1000F.
Peoples heard explosions. What is the sound of an explosion made of? It is fast air displacement. What does floors collapsing creates? Air displacement. Puff of smokes? Air displacement. Take a piece of steel and pull on both ends until is breaks. That will sound like an explosion. The floors collapsing broke many steel beams, that is more explosion sounds. Sound is also slower than light so depending on the distance, the explosions had nothing to do with the results seen. The dust and debris will also appear way later than the sound and light, one more detail that was ignored.
