Look, have you ever studied what happens when mass M at speed V hits another mass M in its path? The speed drops by ONE HALF!
That is true but only when and if the masses are the same, M1 = M2. In the case of these buildings, the top floors and materials falling, M1, represent a cumulative mass > M2 in the way. The mass impeding this once they begin falling is only a single floor's mass + surrounding support, if any...however, the mass above is more, so that floor newly hit gets added to the collapsing mass, and barely slows things down at all...then it falls on freely down to the next floor (airspace in between) , smack, that one gives way , and so on, but you know this
seems to have given way first
, allowing the whole outside to fall cleanly...unlike the main towers, it seems this one fell apart from the roof down into the interior (beginning .11-.12 secs), leaving the outside unsupported (time .20 in the video I posted). In the case of the big towers, they pancaked on down, due to the many floors falling from above them.
Anyway, all the conspiracy people have to much invested in believing gubment or whomever did it, and will never give up that belief, even in the face of new evidence.
That's my belief, and why I should have just stayed out of this.
I went to pilot 'truth' site, saw the NTSB videos, and the path that plan took, and it was so leisurely, and so simple, even a rookie like me with only 120 hours, not 600+ could have done it. "Oh look how expertly that wheel/stick is tended to, impossible." Right. Nothing extreme at all. Again, that guy's problem was landing, not flight itself. He didn't have to land here. No landing gear problems either. Whoa, turning off the transponder, who'd a thunk it? They did, apparently...and that's not even a good talking point. Not like they weren't advised about the planes in some fashion, I am sure, or they didn't have a Sporty's Full Dashboard poster to look at for the things. http://www.pilotshop.com/cockpit-poster-757-p-5281.html
Again, ground effect not much factor, any sufficient amount of forward stick would have stuck that plane. It's angle of attack that's important, even when in ground effect. Just push harder, it'll dive right in.
I will look in to the dispute about the MSL measurements...but what did cut those lightposts? Why did witnesses see a plane fly into the Pentagon? Why were there plane parts inside and out?
Well, despite how it might feel nice to think it was a conspiracy, it was because a plane actually hit it, flown by a fanatical whackjob.
