Police officers were reporting that the building was buckling and in danger of collapse and shortly afterward, the building buckled even more just as it began to collapse. That is a clear indication of imminent heat-induced structural failure.
What do you think initiated the fires in the WTC buildings? What caused this fire after a small airplane impacted this building?
The plane's hitting the building initated the fire's at the point of impact, primarily due to the jetfuel.... but what about the fire's in the part's of the building away from the point of impact ???
The picture You posted prove's my point, thank's
While there was a fire at the point of impact and in the immediate vicinity of the impact, the building was not on fire in other part's of the building and the building did not collapse due to the fire initiated by the impact
Now Why dont You actually answer my question's that I have asked, as I have done for the question's You have raised ???
