This is an intense fire.
NIST and truss(t)

NIST advances a theory that the entire "collapse" was caused by a beam disconnecting itself from its column supports
through thermal expansion, nothing about "a huge section of the North Tower" hitting it as you're claiming.
In fact, NIST tries to minimize the theory of debris causing the collapse of WTC #7 in its 2008 report - the latest and last one.
"In the new Report, NIST quietly drops the theory promoted by since 2001 by the New York Times and FEMA, that diesel fuel was responsible for the collapse,
and minimizes the role of purportedly extensive damage from the fallout of the North Tower. "
Sure it's possible, but not visible in any videos of the collapse.
In this case, it looks like it came down from the bottom up, not from the top down.
If you have evidence of this, I would honestly like to see it. Link?
Seen the video above that you posted and while it was non-explosive, it was also VERY controlled with wires. Not random and chaotic with debris and office fires (which cannot melt/compromise structural beams).
So you believe
one internal CORNER column gets compromised
out of 58 perimeter columns and
25 core columns +
some fires that aren't intense (as one can see in the videos) and
that's all it takes for this building to come straight down symmetrically?
To play the percentiles game just for fun
1 column out of 58 perimeter columns =
1.7% of the perimeter columns.
1 column out of 58 perimeter + 25 core coumns =
4% of the total columns.
Man, the WTC complex was incredibly unlucky that day.
It's a good thing Larry Silverstein took out a new insurance policy for $7 billion weeks before the attacks. lol
