I think you have a serious case of ''whooshing'' going on in your head.
Just because you try and exlain something a few times does not make it right - as in this case.
I do look at the signs - that's why your explanation is to say the least..... laughable.
WTC7 came down without any plane touching it but walls on the upper floors of the Pentagon remain untouched after a plane crashed into it. Only some misguided dunce like you could believe this without questioning it
