Still waiting to hear how a steel-framed building storey with very little concrete "pulverizes" itself against the one below it, which, according to your model, must also be pulverizing, and then repeat this 80 to 90 times through successive storeys of steel-framed structure, at the rough average rate of 0.18 seconds per floor. While simultaneously rendering furnishings and human bodies into particles and fragments and spewing them laterally and upward.
If the floors didn't pancake (and bedunkers still can't seem to agree on this point, since their model needs to explain all the consequent evidence) what did they do?
I invite Major Tom to offer a pulverization model as well.
Put a piece of concrete on concrete. Or on massive steel.
Slam another piece of concrete hard on it. Or a piece of massive steel.
Observe.
The floors fell down from an average height of 200 meters. So to get a feel, drop a big piece of concrete (say, one tonne) onto concrete from 200 meters up.
Observe.
Now drop a big piece of concrete (say, one tonne) onto concrete from 200 meters up, but this time place your body underneath.
Observe.
The floors had, on average, about 140,000 tons of steel, concrete and stuff fall onto them, at an average speed of roughly 21.5 m/s (77 km/h, 48 mph). That's the speed attained after 2.2 seconds of free fall, from a height of 23.5 meters / 77 feet.
Now drop 140,000 tons of steel, concrete and stuff (to visualize: that might be a solid block 63x63 meters wide and about 7 meters high/thick) onto a concrete slab from a height of 23 meters.
Observe.
Do the same, but this time place your body underneath.
Observe.
Just so you get a feel for the masses, forces and energies involved
As for pancaking: Yes. Did happen in the total collapse progression phase after release. Could you show, by way of quotation, who in this sub-forum denies this?
If you want to model pancaking: Each floor took part in 109 floor-floor collisions. Each collision occurred after a vertical distance of about 3.6 meters was diminished by a fall.
So take a piece of floor slab.
Drop it 3.6 meters onto another floor slab.
