Jocko, It is the logical concatenation of what had to happen following the initiating of even one floor falling on another. As two floors fall, the third is added. I am using the logical series of physical events that MUST occur using the science we KNOW occurs. These thing are reproducible. You compress a gas that quickly by 180 times to 2700 PSI, it will get so hot the electrons are stripped off. A gas with free electrons is, by definition, a plasma. This is SCIENCE. Those electrons were seen in the clouds as lightning. Ergo, it happened.
Concrete spalls at just a few HUNDRED degrees Centigrade in normal pressure atmosphere. I checked this to be sure. But at 2700 PSI, it REALLY can shatter. All the water that's still in the cement that holds concrete together is removed and what is left, a form of clinker, is only a fraction of the strength of the original concrete. STEEL BURNS in high pressure at 4400º F and that's a low temperature for a plasma.
The thin steel doors of the elevators are nowhere designed to withstand 2700 PSI, 180 atmospheres of pressure. They will give way. They aren't sealed. The stairwells have one hour rated fire doors. . . but that assumes a normal fire, not something that's under huge pressure caused by thousands of tons of falling debris.
Jocko, I was just in Yosemite last weekend. There was a rockfall off of El Capitan a few years ago of about 1,000,000 tons of rock. The ranger told us that HURRICANE FORCE WIND those rocks created in falling destroyed several houses in the staff residence area over a half-mile away from where the rocks wound up. People one mile away were blown off their feet. The sound was like an extended sonic boom. That's the kind of air-pressure falling debris can create moving the air out of its way.
To demonstrate this phenomenon for yourself, take a four-foot x four foot piece of ¾" plywood and just drop it from three feet onto a flat floor and feel the wind and hear the sound that makes. Now, multiply that piece of plywood by 2,500 all connected together, all doing the same thing, inexorably dropping 15 - 16 feet in the time frame of less than a tenth of a second! That's the air-ram piston of just ONE FLOOR of the WTC Towers. . . and there were 104 of them in each tower!
This is the logic chain I am following. It too is inexorable. I can find nothing to block or stop this cascading series of events. I know physics. I know analysis of what happens. Every step is defensible and follows the laws of science. These are the falling dominoes of the events that must happen after the failure of the first couple of floors. These events and the high-pressure (based on Boyle's LAW) plus plasma physics explain what happened to the concrete and steel of the missing floors and even the central core.
Frankly, Jocko, unless we go with the "floors" flew away (which, in a way, they did as dust), or the floors were transported to an alternative dimension type theory, this is the only really viable explanation. It covers all the observed facts.
Actually, your explanation omits the exterior walls enclosing each floor. Think what happens when the opressure pushes on those walls at each floor. What I am pointing to —the exploding outer walls— is not seen on 911. In fact the image is more one of peeling a banana, with massive center column beams levitating and multistory steel turning to dust while standing. That upper thirty-five floors which tipped to over the street below not arriving at ground level is also counter to your plasma theory..
