This is splitting straws and ultimately irrelevant, there is lateral force when there should be none. How do you explain multi ton pieces flying upwards of 80 mph, and ending up 600 feet away?
Because you can't understand how something works, doesn't mean it didn't happen, you are basically making an argument from ignorance fallacy. It need not be explained how, to show that it did. Are you suggesting explosive force cannot be directed? These lateral high speed ejections prove a force other than gravity is at work.
How do you explain multi ton pieces flying upwards of 80 mph, and ending up 600 feet away? Kinematic analysis proves the NIST-Bazant theory to be invalid, there was no gravitational collapse, case closed.
This thread title is spurious, there were most definitely ejected multi ton pieces.
There is no evidence that the so called "expulsions" traveled at 80 mph. All the columns which fell away followed the basic law of trajectories. The furthest measured steel from 1wtc was at the Winter Garden across West Street. It's max horizontal velocity... toppling from the 80th floor or so was about 35 mph.
What appears to be material flying upwards is mostly material left behind as the "bottom fell out" and the building collapsed down.
In order to explain what happened you need accurate observations and knowledge of mechanics. Otherwise you are dealing with garbage in garbage out.
