Such a question already exists.
Is there anything inexplicable about how the WTC Twin Towers collapsed?
However, this question is marked as a duplicate with the following note from the OP.
NEXT DAY...
I don't have the rep to delete my own question here. But this other question, although primarily about Building 7, has very good answers covering everything I wanted to know. My apologies if anyone feels I have wasted their time asking again.
The cited duplicate, however, cannot address some of the most common claims regarding the Twin Towers.
For example, many claim that the top-down collapse violates Newton's third law.
Similarly, it is often claimed that the visibly rotating top floors of the South Tower should have fallen off and arrested the progressive collapse, as per Newton's first law.
Moreover, sideways ejections of large debris is often claimed to not be consistant with a gravitational collapse ("gravity acts vertically, not laterally")
These claims cannot be addressed in an answer about Building 7, as they do not apply to Building 7.
Should this question be reopened? Should it be rephrased? Or should a new question be asked?
