The trade center weight was carried by it's outer skin, not by a set of girders like that building in Spain.

That is not at all true of WTC-7. WTC-7 was just a typical box style steel framed building with steel beams throughout. It was not the skeleton design that was used for towers 1 and 2. So, that explantion for WTC-7 collapse is not acceptable, because it is irrelevant. The fact is steel framed buildings like WTC-7 prior to and since 9/11/01 have NEVER collapsed due to fire and that is a 100% verifiable fact that people chose to ignore. What brought down WTC-7? It was not fires, they were not even hot enough to melt or deform steel, there was no jet fuel, the fires were limited and had not burned for long and infernoes that have lasted for over a day have not been able to bring down steel framed buildings prior to or since 9/11/01, so the whole idea of WTC-7 collapsing stinks to high heavens. It smells big time! It smells as bad as the CIA offices that were housed within WTC-7 and all the dastardly deeds orchestrated over the years from those same offices.

The trade centers weight,both towers,was carried by both the outer skin vortex via open web lightweight steel trusses and the inner center structural concrete encased steel core. Each floor's weight was independently carried by that floors center structural steel encased concrete core and the outer structural steel skin. The failure was a compromise of both the inner and outer structural standpoints from the initial kinetic load impact from each plane and the fire load generate as a consequnce from within. A matter of time dictated the load failure via the concentrated heat effect on its steel open web joists. That effect was dependent on event cause and effect independent of each particular event. Each plane's damage had an independent cause and effect relationship via angle of decent,air speed at time of impact and fuel load dispersion patterns.

WTC 7 was a acknowledge failure of mind by the FDNY and its owner via a severe lack of water. The lack of water was a direct consequence of that buildings failure. The available resources just prior to her collaspe were better position on the potential rescure/recovery efferts already underway against the indisputable lack of water resource available to fight such fire spreading in WTC 7.
