Debris was blown away from the building with a powerful blast. The whole building came straight down and the overhanging section was never seen again.

The centre of gravity was BARELY off centre, and what's imprtant is that it was nowhere NEAR being outwith the base of the structure, which would be required for the whole thing to tip over the way a tree does when it's felled, hence why it came straight down. I've drawn a little picture to help you visualise that
It's a cross section at any one of the 22" spaced supporting pillars.
The black dots represent the centre of mass of each of the two "halves" of the building. The centre of mass for the whole thing will lie at a point somewhere on a line between those two dots.
Gravity always acts straight downwards, and there was nothing providing any horizontal component. There will have been a turning moment about the stronger side of the building at the point I've marked as
B leading to the tipping. As the pillars failed on the left hand side as seen here (allowing the tipping) the load on the pillars on the right hand side will have increased. At some point they'll have had more load than they could bear; at this point THEY failed and the top section collapsed onto the 75th floor, which couldn't on its own support the top 35 floors, so IT failed, falling onto the 74th floor... etc etc.

yup, failing concrete does that!

What's unusual or conspiratorial here? Put a tissue on your desk, drop a magazine next to it and watch the tissue flutter sidewise. When things move through air quickly they cause that air to move. Doesn't mean there's explosives present. Ask hoody about this

This is very unclear. WHAT would not be uniform, and in what way wouldn't it be? Really don't know what you mean by this, but again, the centre of mass was still well within the base (this would always have to be the case unless a very large force acted sideways on the building, but even the plane crash imparted a tiny fraction of the horizontal force that would be necessary to change this), so the building as a whole didn't tip. You'd be surprised if apples fell off trees sideways, right? Gravity acts DOWNWARDS.
