Why, oh, why, am I so dense and thick-headed as to be unable to see what's so clear, reasonable, obvious, common-sense, undeniable and downright glaring to Christophera.
I must admit, I have no idea what rate a collapsing building should fall, nor how large the rubble tends to be. To my naive mind, the collapse should accelerate rapidly as more and more weight bears on the structure below. At the end, it seems to poor old stupid me, the building should be falling somewhere near 9.81 m/s/s.
After such a titanic impact, I wouldn't expect much to be left, either. I can shatter concrete with a sledgehammer blow, much less than the impact of a skyscraper.
Christopera, can you PLEASE abandon the "it's obvious", "it's undeniable" and "it stands to reason" tags and accept that it's NOT glaringly clear to us mortals. Leave common sense aside in favour of cold, hard facts.
I'd like to reiterate what has been asked many times before:
How fast should a large building fall if it collapses due to an airliner impact?
From what basis is this speed derived?
How is this different from a collapse caused by demolition explosives?
What difference would you expect to see in rubble size between a large building collapsing after an airliner impact and one being demolished?
Again, how do you know this?
In fact, I don't expect you to answer, Crhistophera, because I don't think you have anything. I expect if anything a round of "As any reasonable person could see" and so on.
However, I think I am a reasonable person, and I can't see.
If you won't even have a stab at answering these questions, I call troll. You're just wasting bandwidth with these unsupported, didactic assertions.
