There is no way that the fuel from the plane that hit the South Tower could cause enough heat, so that it would penetrate the concrete enough to weaken the steel enough, so that the building would come down into its own footprint, in a fall-time of 11 to 14 seconds. The odds against something like this happening without controlled demolition are great enough that it couldn't happen this way.
Hi BADecker. These statements are a bit difficult to interpret. Let me try to find simpler statements that might correspond to what you're saying. You can clarify if I am misunderstanding you.
First, there are preconditions without which the sentence makes no sense.
(1) A plane X hit the South Tower.
(2) The fuel from X caused a fire Y in the South Tower.
Presumably we all agree on these. After this things become less clear.
Here's something you might be asserting:
(3) The fire Y could not have caused the steel girders in the South Tower to weaken enough to cause the South Tower to collapse.
Are you asserting (3)? If you are, then we could discuss this simple proposition. However, I think Spendulus has already done calculations to argue against this. I haven't checked his calculations, but I'm willing to.
If you are not asserting (3), then I think you're probably asserting (4) and/or (5):
(4) If a building like the South Tower were to collapse due to steel girders being weakened, then the debris field would have a maximum* radius of R meters with probability P.
The "maximum radius of R meters" in (4) is to interpret "come down into its own footprint." I think you're suggesting that if the official narrative were correct, the debris field should be larger than the "footprint." A strict interpretation of "footprint" would mean the radius R equals the distance from the center of the South Tower to one of its corners. I suspect you don't really mean that. You probably mean an R bigger than that, since it's clear that the debris field was not confined to where the South Tower stood. Do you already have an idea what the radius R of the debris field is?
The reference to "with probability P" in (4) is suggested by your second sentence "The odds against ..." It seems like you're not saying such a collapse is not impossible, but improbable. How improbable? Less than one chance in 100?
Before going on, is (4) an accurate restatement of part of what you are saying?
I haven't included your reference to the time required for the collapsed. I would restate that as follows:
(5) If a building like the South Tower were to collapse due to steel girders being weakened, then the collapse would take less than T seconds with probability P'.
I said "less than T seconds" because I think you're suggesting that it should have collapsed more slowly if the official narrative were true, right? Again, "the odds against" suggest you think P'(T) with T between 11 and 14 would be low. How low? I haven't verified that the time for the collapses were between 11 and 14 seconds. I can if it becomes relevant.
When you respond, it will be helpful if you refer to the numbered statements (1) - (5) to avoid confusion. Which of (1) - (5) are you asserting? All of them?
* In the original post I wrote "minimum" instead of "maximum" here. As I've said before, trying to be precise is tricky.
