indeed.
why then, did the top part crumble first? the floors up to 78ish are the ones that are supporting the alleged big chunk which will serve as a piston with which to crumble the building. this big piston has no weight on top of it. why is it the first thing to dissolve?
the top part(spyre) was nearly flush with the compromised floors before those floors began to cascade in near free fall.
so in short. the bottom three quarters of the building were completely unaffected as the upper floors crashed down onto them. it wasn't until this big alleged piston had turned to dust that the bottom part started to fall. watch the video.

Imagine. According to the media/government fable, it was hot enough to soften the steel and cause the building to collapse, however, as is evident from the picture and video, it was not hot enough to singe her hair.

This article from Chief Engineer magazine presents eyewitness account of the moments after the first plane crash, and describes evidence of large explosions in the lobby, parking garage and subbasement levels of WTC-1 at the time of the crash
It contains some fascinating first-hand accounts of the events of September 11 as recounted by operating engineers on the scene. One of the most remarkable is the story of Mike Pecoraro, who was working in the 6th sub-basement of the North Tower when the first plane hit. Here are some excerpts:
At about 6:45 he went to the mechanical shop in the second subbasement, ate his breakfast and chatted with his co-workers who were also arriving for the normal 8:00 a.m. beginning of their shift. Mike’s assignment that day would be to continue constructing a gantry that would be used to pull the heads from the 2,500 ton chillers, located in the 6th sub- basement level of the tower. 49,000 tons of refrigeration equipment were located in the lower level of the tower. The 2,500 ton units were the smallest in use...
Construction worker Phillip Morelli describes being thrown to the ground by two explosions while in the fourth subbasement of the North Tower. The first, which threw him to the ground and seemed to coincide with the plane crash, was followed by a larger blast that again threw him to the ground and this time blew out walls.
Frank A. DeMartini, Manager, WTC Construction and Project Management, discusses the fact that the WTC towers were designed to take multiple hits from airliners and not collapse, comparing it to poking a pencil through fly netting, DeMartini was adament that the towers would not collapse. DeMartini died in the towers on 9/11, this interview clip was taken from video shot in January 2001.
The following letter was sent today by Kevin Ryan of Underwriters Laboratories to Frank Gayle of the National Institute of Standards and Technology (NIST). Underwriters Laboratories is the company that certified the steel componets used in the constuction of the World Trade Center towers. The information in this letter is of great importance.
Dr. Gayle,
Having recently reviewed your team's report of 10/19/04, I felt the need to contact you directly.
As I'm sure you know, the company I work for certified the steel components used in the construction of the WTC buildings. In requesting information from both our CEO and Fire Protection business manager last year, I learned that they did not agree on the essential aspects of the story, except for one thing - that the samples we certified met all requirements. They suggested we all be patient and understand that UL was working with your team, and that tests would continue through this year. I'm aware of UL's attempts to help, including performing tests on models of the floor assemblies. But the results of these tests appear to indicate that the buildings should have easily withstood the thermal stress caused by pools of burning jet fuel.
There continues to be a number of "experts" making public claims about how the WTC buildings fell. One such person, Dr. Hyman Brown from the WTC construction crew, claims that the buildings collapsed due to fires at 2000F melting the steel (1). He states "What caused the building to collapse is the airplane fuel…burning at 2,000 degrees Fahrenheit. The steel in that five-floor area melts." Additionally, the newspaper that quotes him says "Just-released preliminary findings from a National Institute of Standards and Technology study of the World Trade Center collapse support Brown’s theory."

perhaps it's just easier to believe in 'magic bullets' and whatnot

Shouldn't the building of fallen outwards, not in on itself?

No, that is what you are pushing...magic bullets.
Did you not see my post above that clearly shows that at least 3 floors up and 3 floors down from the impact floor were obviously at extreme temperatures? Do you not understand that when one floor (most likely the impact floor) gave that now we're looking at an almost 30 story building falling through as much as 60 feet? Can you not conceive of the kinetic energy involved in that? and that the inertia involved in that falling building was not going to stop? All it had to do was take out 10 feet - one floor - a floor whose mass would be added to the falling mass on the next 10 feet - one floor - and so forth and so on, all the way down to where your coveted melted steel landed. (I'm not sure where you going with that by the way.)

All of these accounts of explosions in the basement were from the exploding fuel – air mix that fell down the elevator shafts when the planes impacted, the buildings collapsed much later.

Didn’t we just go over this a couple of pages ago? Air pressure from the collapsing floors, plus the movement of the exterior frames caused the windows to pop out. True demolition charges look and sound totally different. In fact there is no audio evidence to support the demolition charge claim.

Billybob, steel for all of its wonderful properties is really not that strong and rigid when you scale it up to the size of the WTC.
Buildings derive their structural strength from how the steel is put together, in connection to the use of other materials (i.e. the rigid floor slabs). Once the building started to drop, the precise alignment of the interior columns with the floors and exterior wall would be quickly compromised. The floor slabs on the upper floors would quickly break up, and the top of the building would not really have much structural integrity left. It would kind of be like a falling bowl of spaghetti. At the same time the falling mass pushed the outer walls of the lower portion outward, accelerating the failure of these floors.
Now as for the spire in the north tower, the fact that that started to drop firs indicates that the collapse started with failures in the core area.
This is consistent with the fact that the airplane impact on this building was more centered and caused more damage to the core area.
The falling mass undoubtedly caused floors above and below the initial point of failure to fail at the same time. It is really hard to tell with all of the debris and dust flying around.
is this really our experience of concrete and steel even under a comparatively small judder and burn of residual (in the case of tower 2) jet fuel and furnishings?
