I have watched the conspiracy theory videos previously and I find them compelling, and parts of them certainly seem like they could be true. However anyone who blindly believes what they are shown in the conspiracy theory videos is even worse than people who blindly believe what the mass media has said for years. If you didn't conduct the research yourself and you are not an expert in these fields of study you cannot say what is true and what is not (just as I cannot). You can choose to believe information from whatever source seems the most credible to you, and I will almost always choose the mass media and not the faceless creators of videos on the internet. I know that some eye witness accounts have said they thought there were bombs in the building but there are many more eyewitnesses and experts who would never back such a story.
I'm the kind of guy who believes that we did in fact send men to the moon and that there was probably only one shooter in Dealey plaza. I do believe that the holocaust happened and that the World Trade Center was brought down by terrorists and not the American government. There are many conspiracy theorists who would claim otherwise, but none of them can prove their position is the truth any more than I can.
I would like to believe that I wake up every day and conduct my daily business by my own free will, and that everything I encounter in my life actually exists. Of course I cannot prove that any of that is true...Everything I experience in my life could be images created in my head and I could actually be living inside the matrix. Or I could be a character in the video game or story of some much more advanced creature than I can imagine.
So yes, everything we are told could be false and the entire world could be a conspiracy, but I hope and believe that its not true.
well im not a structural engineer but I do know that jet fuel (kerosine) doesnt melt, bend, or break steel beams and the cores of steel buildings, it also doesnt pulverize concrete into pcs smaller than a wrist watch.
So to some it up....you better go ask for your money back, that college of yours did you a diservice...also please stay away from designing any steel framed buildings, you obviously have a turd for a brain.
here is a 20 second video im sure you can understand, even with your pee size brain.

What About the Fires?
The official story maintains that fires weakened the buildings. Jet fuel supposedly burned so hot it began to melt the steel columns supporting the towers. But steel-framed skyscrapers have never collapsed from fire, since they're built from steel that doesn't melt below 2750 degrees Fahrenheit. No fuel, not even jet fuel, which is really just refined kerosene, will burn hotter than 1500 degrees Fahrenheit.
Steel-framed skyscrapers have never collapsed from fire.
It's also odd that WTC7, which wasn't hit by an airplane or by any significant debris, collapsed in strikingly similar fashion to the Twin Towers. There wasn't even any jet fuel or kerosene burning in WTC7.
According to the 9-11 report by the Federal Emergency Management Agency (FEMA), “the specifics of the fires in WTC7 and how they caused the building to collapse remain unknown at this time.”
Aside from its startling nonchalance, this statement makes a rather profound assumption. Again, no building prior to 9-11, in the 100-plus year history of steel frame buildings, had ever collapsed from fire.

The flattened ruins are WTC1 and WTC2 (in the middle), and WTC7 (at the bottom)
This fact was known to firemen. Hence their unflinching rush up into the skyscrapers to put out the fire. Partly it was bravery, to be sure, but partly it was concrete knowledge that skyscrapers do not collapse due to fire. Yet after 100 years, three collapsed in one day.
Did the FEMA investigators not think to ask the New York City Fire Department how they thought the fire started, or how the fires could have caused the astounding, historical collapse? This would seem to be an elementary step in any investigation about a fire. Instead, they chose to leave the cause of the collapse "unknown."
Conclusion
So if the science in this article is correct (none of it goes beyond the tenth grade level), then we know that the floors of the three WTC buildings were not pancaking but were falling simultaneously.We also know that fire is an insufficient explanation for the initiation of the collapse of the buildings.
Why, then, did the three WTC buildings fall?
There is a method that has been able to consistently get skyscrapers to fall as fast as the three buildings of the World Trade Center fell on 9-11. In this method, each floor of a building is destroyed at just the moment the floor above is about to strike it. Thus, the floors fall simultaneously — and in virtual freefall. This method, when precisely used, has indeed given near-freefall speed to demolitions of buildings all over the world in the past few decades. This method could have brought down WTC7 in 6.5 seconds. This method is called controlled demolition.
A controlled demolition would have exploded debris horizontally at a rapid rate. A controlled demolition would also explain the fine, pulverized concrete powder, whereas pancaking floors would leave chunks of concrete. Controlled demolition would also explain the seismic evidence recorded nearby of two small earthquakes — each just before one of the Twin Towers collapsed. And finally, controlled demolition would explain why three steel skyscrapers — two of which were struck by planes and one of which wasn't — all collapsed in essentially the same way.
