Momentum would continue onward without resistance - but there's a fucking skyscraper in the way (plus wind resistance, jk).

You're clearly buying into the propaganda.

Step by step and simplified for the mentally challenged boomer:

  1. A floor collapses. You now have one floor of material in free fall for ~15 feet.

  2. One floor of material impacts the floor below with a greater load that its own weight, as it was just in free fall for ~15 feet and has gained momentum. This is just enough force to cause this floor to collapse as well. You now have two floors worth of material in free fall for ~15 feet.

  3. Two floors worth of debris + the momentum gained from the ~15 foot free fall impacts the floor below, collapsing it much easier than the previous impact. You now have three floors worth of material in free fall for ~15 feet.

  4. At this point so much debris has begun falling that the next floor collapses before all the debris has event hit it. You now have 4 floors worth of debris falling, with an increasing amount of that debris falling a greater distance and gaining more momentum before it impacts some part of the building below. When it does hit, the structure is no longer able to absorb the force and sections below the debris are violently thrown downward with more speed and momentum than they would have had from simply breaking off.

Now go back to the beginning of this comment and add around 1/8th of the weight of the building to the initial falling mass.

Hey, Jason is a great guy and all, but we're still reviewing his boomer application. Some of the old-timers are taking a hard line on '64.

I wasn't even alive in the 60s.

You kids. 😁

Not sure if I already said this elsewhere, but that first floor that collapses in his scenario would have quite a few floors above it - Presuming the collapse would begin in the most damaged place.

Haven't studied the videos, and don't remember if it was obvious where the first part to collapse was, in relation to the impacts and fires.

That's aside from steel beams having 45 degree cuts, and other 'oddities'.

And then that peculiar healthy structure below in which you can see explosive detcord and PETN streamlining down the elevator shafts in three floor increments ahead of collapse.
