I disagree profoundly with this whole comment, but I am puzzled by the opening line of
“For over two seconds, WTC7’s outer shell and roofline accelerated downward at around g, the acceleration due to gravity, but this does not imply free-fall and is essentially a coincidence”
Can you explain what you mean by this? I mean if you say it was falling at free fall speed but wasn’t in free fall, then what was causing it to coincidentally travel at that speed?
