How could WTC1, 2 collapse due to gravity forces alone after some local failures up top?
NIST does not explain it and two scientists, Bazant and Seffen, have come to assistance: the upper block is solid (uniform density throughout) and crushes the lower structure like a sledge hammer hitting a house of cards.
In my little article at http://heiwaco.tripod.com/nist.htm paras 1.1 - 1.5 (it takes a few minutes to read) I suggest, using common sense, that the upper block is no sledge hammer and the lower structure is no house of cards.
Actually, if the collapse is initiated as alleged by NIST, the uppr block could only slice some floors of the lower structure before the collapse is arrested; Reason is misalignment of colliding structures and that the lower structure actually destroys the lower part of the upper block until the collapse is arrested after some local failures (a few floors are damaged).
My text has been peer reviewed by some very clever guys that liked it - now it is up to the horrid critics of JREF to find some errors. Good luck. Praise is also welcome.
