Reply #55: Good Description Of What Happens In The 9-11 Scenario [View All]

It almost sounds like you are thinking like I think. Every now and then you come across with a real clear piece of thinking that reflects the actual performance of materials and structure and I recognize it.

Yes it did come apart at the floor beam/box column joints, exterior and interior box columns. There were 2 major explosive areas or directions.

1. The C4 coated rebar of the core.

2. The C4 layer between the corrugated steel panels and the lightweight concrete poured onto it.

I have sources that are not fully credible but do provide explanation for the disintegraton of the structural joints. Other sources are. There are people who remember hearing about forced evacuation of workers from the floors just before they were poured. Anyway, my sources indicate that there were virtual puddles of thick plastic poured around all the interior box columns and at the floor beam joints with the exterior box columns when workers returned following the evacuations.

The delay paths detonated 4 floors at 75 MS intervals, then 40 feet of core, repeating until the 48th where it changes to deal with the 2 floors of mostly concrete where major elevator/mechanical equipemnt was.

This photo below is a core detonation instant. Note the fountains of concrete (dark brown/grey) arcing up and out.



and the below is a series of floors detonating.
