Well i know that: 1. Building 7 collapsed without impact of any airplane
Did you know that building 7 (like all of the WTC buildings) is built on marshland/swamp. This single fact seems to elude most(all) conspiracy
theorists wrt 9/11.
2. First Responder - Firefighters heard a set of explosives go off during/right before the towers collapsed
What sound does a lump of concrete make when it hits the ground whilst traveling at terminal velocity?
Is it possible that rubble falling from within the either WTC buildings could have fallen down elevator shafts?
What sort of influence would the elevator shaft have on the acoustics of such a sound?
If there were explosives, why didn't any of the firemen/police/paramedics find evidence of such. As an engineer, I have seen/sifted rubble after
controlled explosions.....there are always bits of det-cord, paper and det-joiners left after an explosion. The firefighters are trained to spot such
things when working in emergency situations.
This should ring alarm bells if you think the government would instigate 9/11....Firefighters do their job because they are naturally good people who
do what is right. Such people would be vocal about something like explosives if they were found in the WTC's rubble piles.
3. There were pools of molten steel on the ground of Ground Zero, in no way could have an airplane impact caused that.
This is a pet peeve of mine as it demonstrates the lack of knowledge pertaining to matters of metalurgy/blacksmithing/engineering.
How do I manage to melt steel on a coal fired forge if the coal will only burn at x degrees celcius?
If you look at the theory....it is impossible using coal.....Yet I can melt steel on a coal forge easily.
4. Many Engineers and Architects have said that the Towers could have with-stood many airplane collisions due to their steel-concrete
Well, I'm an engineer and I disagree (before you jump down my throat..yes I have looked at the building design and foundation specifications
extensively...and then some). The WTC1/2 buildings were built in a unique fashion using techniques that were considered pioneering at the time. The
WTC1/2 both have a lattice based steel frame that utilises geometric strength to allow it to be built with far less weight than the traditional
reo-concrete that was used at the time. This kind of design is incredibly strong whilst whole, but will weaken significantly if the structure is
compromised in any way. Combine the loss of structural integrity with an intense fire fanned by wind and you have the recipe for disaster.
These days, skyscrapers are built using pretension so we can build them even lighter, yet with far greater strength.
Conclusion... I am not siding one way or the other, but, I have yet to see a conspiracy theory based on 911 that is plausible. Though I will keep
