Anbei ein Auszug aus einer hervorragenden Diskussion im "Debunker-Forum" JREF. Es geht um die pysikalische Unmöglichkeit der Kerosin-Explosion im Untergrund.
Die Diskussion ist auch sehr erhellend, wie seitens vieler "Debunker" vorgegangen wird: Persönliche Anfeindungen und Bekämpfung von zugeschobenen Standpunkten (Strohmänner).
Now what you can do that NIST did not. Take an image of the elevator shafts and trace the fireball path that caused the destruction in the lowest levels of the basement of the North Tower. Then match that up with the eyewitness accounts and testimony of survivors. Just to clue you in, you can't do both and arrive at the conclusion the official story tells us without the use of something else in the sublevels of WTC: North Tower.
All of the above information should bring us to the logical conclusion that a fuel-air explosion did not travel hundreds of feet down the main freight elevator shaft of WTC1, from the impacted floors to the basements, to cause structural damage to the basement floors and lobby. Car 50 was the only elevator with access from the impacted floors of WTC1 to the sub levels B6 and below, and its operator survived, having experienced no explosions or fireballs down the main freight shaft.
That such a fireball could have traveled down Car 6 has not specifically been ruled out by the above information, but it could not have extended beyond sub level B1, whereas explosive events caused much destruction on lower floors.
Also, considering an FAE traveling down this shaft sufficient in strength to destroy a machine shop in the basement levels (as per Pecoraro’s testimony), even if this elevator had access to this floor, and cause elevators servicing the lowest floors to blow out (as per Walsh’s testimony), as well as additional structure damage in the basements, it seems extremely unlikely, if not impossible, that the shaft itself, and neighboring floors all the way down would not be similarly destroyed by the massive over pressures accompanying this FAE down the building. Put simply, an FAE moving down an elevator shaft and causing severe damage in basement levels with massive force, could also be expected to destroy the shaft itself, especially since this shaft would be a very confined area, and its wall supposedly not reinforced by any concrete in the walls or etc.
The visible fuel-air explosions caused by the impacts visibly failed to destroy even the outer perimeter columns of the impacted floors, or to even remove their aluminum cladding, which was only fastened on and not solidly connected. Only the plane impacts themselves severed perimeter columns or caused such damage to the aluminum cladding. There is no evidence of great over pressures from the fireball itself if it traveled down the shafts either in the interior or exterior.
How, then, could a fireball that failed to remove this aluminum cladding in its immediate blast, travel down over a thousand feet of an unprotected elevator shaft and maintain sufficient over pressures to shatter concrete and steel fire doors, and cause a cave in at level B-4?
It has already been shown that the operator of elevator 50, the main freight, did not even experience a fireball, let alone life-threatening overpressures. This fits logically with the lack of exterior damage shown above.
More realistic explanations of the WTC1 basement events, including the use of secondary explosive devices, should be considered.
