This whole thread just shows ignorant people jumping to conspiracy theories when they cannot understand some facts or explain things.
Long ago, people had explained lightning by invoking “Lightning gods” and other imaginary entities. It is probable, though I am not an expert in lightning, that even today, we cannot explain all aspects of what creates lightning. There are still gaps in our knowledge. Accept the fact that there will always be gaps in our knowledge and there is no such thing as omniscience. An individual’s knowledge is very limited and so there are many things that they could not explain by themselves. That does not mean that they should jump to conspiracy theories if they cannot explain how +10,000 gallons of burning kerosene could weaken steel trusses supporting a floor and cause the trusses to collapse.
Accept the fact that skyscrapers are not built like bunkers and there is no building code that says that you must be able to burn 10,000 gallons of jet fuel on 3 or fewer floors without the building collapsing.
The jihadis tried to blow up the building from below and get one tower to crash into another back in 1993. If they were successful, I’m sure we would have seen all sorts of conspiracy theories about Clinton and the CIA, etc.
One of the proponents of a 9/11 conspiracy theory is a 47 year-old graduate student with too much time on his hands.
