Going to post a reply to this one from earlier.
And over half the American public (including you) is therefore ill-informed of the actual structural implications of a plane hitting a building. Mass belief does not equal truth.
Again, watch this video, made by a highly regarded architect, who began a site in which 1500 architects and engineers have signed a petition to begin an independent ingestigation:
An architect is also not qualified to make such statements. It is not his field, it is the field of a structural engineer.
and you will see what it really takes to bring down a steel skyscraper. A building like this doesn't come down merely with gravity, ESPECIALLY at freefall aceleration.
It is not coming down 'merely with gravity', it's come down with gravity after sustaining serious damage. Also there is a significant difference between freefall (which is what you claim) and near freefall (which is what actually occurs). For simple proof of this watch in a video of the collapse how rubble falls down the side of the building at a greater rate than at which the building collapses.
Steel is a VERY VERY strong material, relatively light, with TREMENDOUS weight bearing capacity, and doesn't even BEGIN to weaken until temperatures much greater than what we know were present in the buildings. The WTC had dozens upon dozens of large steel beams, including massive thick core columns. The floor pannels were both welded AND bolted to the outer steel columns, as well as the thick inner core. Yet people actually believe that in a blink of an eye, thousands of these bolts simply popped, and 10 floors are brought down within ONE SECOND.
This is simply not true.
The fires in 9/11 were well and truly hot enough to severely weaken structural steel.
Also, with regards to the explosives, there are HUNDREDS of different types of explosives, all with varying degrees of volume, flashes, destructive force, etc. You really don't think insiders within the government don't have access to some relatively silent explosives that don't emit bright flashes?
Not to mention, people DID hear them.. Litterally HUNDREDS of witnesses reported hearing and feeling explosions after, and even BEFORE the first plane hit. William Rodriguez, the last person out of the WTC, reported to hear an explosion in the basement, litterally pushing him UPWARDS, then seconds later, he heard the plane hit in the distance near the top of the building.. Again, explosion... BEFORE the plane hit! Sooo, what's the story here? Do you think this man is lying? People were reported seeing and feeling walls caving in in the basement, and getting injured and even killed by them. There was even a man in building 7 constantly hearing explosions around him (remember, NO plane hit building 7), who reportedly barely made it out alive as floors were caving in around him. This is also the same man who mysteriously died, just days before the NIST report of the Building 7 collapse was released.. Hmmm. There are litterally red flags EVERYWHERE.
Oh, and another important tidbit.. Physicist Steven Jones, actually FOUND evidence of explosive thermite residue in the WTC dust. And yes, this was throughouly tested. The particles contained the near exact footprints of thermite. No other material in the building could have given this readout.
But no... there were no explosives >_<
This stuff isn't that hard to find, people. The information is litterally AT YOUR FINGERTIPS. And it isn't just speculation. It is scientific fact. Don't take my word for it, do some research for yourselves.
Ok I'm taking this part as a whole because it is entirely self-contradictory. You talk about 'thermite explosives' - thermite is non explosive. It reacts to cause extremely high temperatures but never explodes, if they used thermite to demolish the building then there would have been no need for explosions.
