THERE WERE NO EXPLOSIVE CHARGES PLANTED IN EITHER TOWER NOR WERE THERE ANY IN THE PENTAGON.

I know this is not the World Trade Center.

Notice the small flashes at about the 0:20 mark. Those flashes are the result of the demolition explosives detonating. Notice how the building fell within seconds of them detonating.

This is a video of Tower 1 collapsing at around the 0:29 mark:

Notice how there were no flashes of light. Notice how the tower started to collapse before any smoke came out (ignoring the obvious smoke from the fire.) There was no explosive detonation. The fireball you see a few seconds latter was likely the result of burning material being ejected from the building as the upper floors collapsed on top of it.

But I know some of you are going to try to argue that said fireball was a controlled detonation, so let me put that theory to rest.

Care to guess how explosives work?

When an explosive detonates, a violent exothermic chemical reaction occurs. Exothermic reactions release heat. These reactions also produce a non-reactive gas. As I hope you already know (or are at least capable of learning,) hot gases expand. This serves to push oxygen (and whatever you were blowing up) away from the point of detonation. No oxygen means no fire. No fire means no Hollywood style fireball.

Still, don’t believe me? Here is a video of an M67 frag grenade (the standard-issue grenade for U.S. troops) detonating at 0:32:

Neither high explosives (designed to shatter) nor low explosives (designed to push) will produce a fireball without some other flammable material being present. They create a puff a smoke, kick up some dust, and that is it. Hollywood explosions are the result of droping a very small charge into a one gallon milk jug filled with gasoline. When set off, the charge produces a spray of gasoline but fails to displace that much oxygen. Microseconds after the charge has detonated, the gasoline spray encounters oxygen, and, given the latent heat left from the primary charge, ignites. This is a deflagration, not a detonation. And sure enough, the pressures involved are MUCH lower (it won’t do major damage to a reinforced concrete structure, though you wouldn’t want to be standing near it.)

So, what brought down the towers? Fire.

“But jet fuel burns…”

At a temperature lower than the melting point of steel. Yeah, I’ve heard that before and its absolutely true. Jet A burns at 1,000oC$1,{000}^{o}C$, but the melting point of steel is 1,500oC$1,{500}^{o}C$.

But guess what. It didn’t need to melt the steel.

Have you ever seen a blacksmith work? That glowing red piece of steel is still very much a solid yet they can bend it with nothing more than a hammer.

Do you know why they can do this? Because metals lose strength when they are hot. The World Trade Center is a reinforced concrete building. It just so happens that a mostly enclosed concrete space functions as an oven. Temperatures soared as jet fuel and office furniture burned.

So, what happened to the steel? It started to sag and placed a tensile load on the concrete. Concrete’s tensile strength is only 10% of its compressive strength. When the steel structure inside the concrete began to sag, it took away 90% of the tower’s structural integrity.

There is a reason the Twin Towers were built to have 100% of their intended structural integrity. Now imagine building it to a tenth of that.

Eventually, the steel on one of the floors grew weak enough that it sagged too far for the concrete to support itself. The concrete failed, transferring its stress to other sections of the floor. Those sections, themselves unable to handle the additional stress, failed. This cascaded until the entire floor had failed.

So now we have a section of the building, easily weighing over 100,000 tons, falling into the floor below it.

Guess what. The floors were not designed to have a 100,000-ton load suddenly come crashing into them from above.

This is called a pancake collapse and this is exactly what happened on 9/11.

There were no explosive, no spec ops posing as jihadists, no government cover-up. This was the result of sub-humans (and if you are going to kill 4,000+ innocent men, women, and children I am going to use that term) flying fully loaded passenger jets into the Manhattan skyline.
