I enjoy the liars demanding how impossible it would be to demolish the three skyscrapers with explosives yet the explanation of the "natural" first ever total collapses of steel supported structures is water off a ducks back.
We have already established that the collapses were not natural. No one here believes that, no one here has used the term in the sense you refer to, and you have been informed time and time again of the fact. Either you are incapable of registering it, or you are lying.
Of course, even the usage of explosives would require several firsts as well, as you have also been informed.
1. First time explosives were planted in an occupied building.
1a. Same, but without detection despite millions of people moving through the buildings in question each week
2. Detonation of explosives without causing barotrauma, even to people inside the buildings
3. Detonation of explosives without blown out windows for blocks around.
4. Detonation of explosives without audio/visual evidence consistent with such.
5. Explosives without being able to knock down walls to weaken structural members.
6. Survival of explosives in two buildings hit by planes, without the plane impact disrupting the explosives or knocking any of them out of the building.
6a. Ability to predict the plane's impact and effects exactly, despite that being dependent on wind speed, turbulence, angle of attack, yaw, and several other entirely random factors it would be impossible to predict.
7. Survival of explosives in areas which had been on fire for an hour or more.
8. Survival of explosives in building which had been on fire for, oh, seven hours.
9. Making the miles of distinctive wiring and casings vanish from all witnesses or visual evidence, despite the thousands of people on site and the fact that the crime scene was the most witnessed and documented in history.
And so on.
People who defend lies can never be convinced of the truth.
Aren't you also a Holocaust denier?
