Oh sure .. it can happen three times in the same day to buildings of different strustures .. never before in history .. three times in the same day .. defies the laws of physcics, science, and engineering .. three times, same day.
Sure ..
The towers were designed withstand the impact of large aircraft with asymmetrical girders throughout the building. The towers stood close to an airport and they took the impact of a plane into the design specifications. The towers were better designed to withstand the impact of a large plane far beetr than other buildings that have been struck by planes .. and didn't melt.
What's your story for WTC7 .. wasn't hit by plane, no significant debris hit it .. free fall speed.
Many lessor buildings have been stuck by large planes .. none ever melted .. but beyond that, the belief that a pplane hitting a building would cause it to collapse uniformly at free-fall speed in decidedly unlearned. You would have to know absolutely nothing about physics or buildings.
Had you been paying attention you would know that I have expanded on the science quite often. It's not rocket science and most students learn them by the 8th grade. I know I did.
The Law of Falling Objects
The Law of Continued Momentum
Newton's Third Law
The Conservation of Energy Law -- An object, as it falls, converts its gravitational potential energy (due to height above ground) into kinetic energy (speed). If that object has to use some of its energy for something else, like pushing air out of the way, then there will be less energy available as kinetic energy so it will take longer to reach the ground. If that object meets any mass resistence as it falls, it decreases the rate of fall even further.
The buildings on 9/11 fell at free fall speed .. which meant that NONEof the buildings encountered ANY resistance during their collapse and feel as id there was nothing but air. Where is the delay that must be expected due to conservation of momentum.. one of the foundational Laws of Physics? That is, as upper-falling floors strike lower floors and intact steel support columns the fall must be significantly impeded by the impacted mass. If the central support columns remained standing, then the effective resistive mass would be less, but this is not the case — somehow the enormous support columns failed/disintegrated along with the falling floor pans.
You cannot replicate such an event in a lab because it is not possible.
It is scientifically impossible that the fires in the World Trade Center generated enough energy to turn reinforced concrete into fine powder in mid-air. Each of the Twin Towers contained approximately 90,000 tons of concrete that was visibly pulverized as it exploded in mid-air.
It is scientifically impossible that the fires in the World Trade Center generated enough heat to threaten the structural integrity of the steel. Even FEMA acknowledged that the jet fuel completely dissipated within the first few minutes after impact. Jet fuel is essentially kerosene it quickly burns out without large amounts of air .. as it did on 9/11.
The Second Law of Thermodynamics -- Heat generally cannot spontaneously flow from a material at lower temperature to a material at higher temperature.
The towers came straight down but debris was blown in every direction .. pulverized debris.
Obviously you attended a different science class than I did so perhaps you can enlighten me on what science supports your conspiracy theory.
And while you're at it please show me where you got the idea that thermite was used in the cleanup.
