8:46 amvFirst plane hits the North Tower of the WTC. Within Minutes officials coordinate the city wide emergency response. Housing the command center was the 23rd floor of WTC Building 7.
9:00 amBuilding 7 was evacuted from the inside. No one knows who issued that evacuation.
10:28 amNorth building collapses. Falling debris ignites fires in the neighboring towers WTC 4,5,6 and 7. Building 7 burns for 7 hours before collapsing.
NoonFloors 7-9 and 11-13 burned out of control. One issue with this building was that the sprinkler system required manual initiation of the electrical fire pumps, rather than being a fully automatic system. This caused a huge hinder, due to the water pressure, in extinguishing the fires. During this time the firefighters heard creaking sounds coming from inside of the building.
2:00 pmFirefighters noticed an unstableness in the building (a bulge in the southwest corner) raising a red flag that the building might collapse.
3:30 pmFDNY Chief Daniel Nigro made the decision to evacuate the surrounding area.
5:20 pmvWTC Building 7 collapses destroying the city's emergency nerve system.
May 2002FEMA issued a report based on their investigation resulting in the idea that the building was weakened by the fires caused by the debris that WTC 1 and 2 helped ignite; the fire was not extinguished or controlled due to the water pressure and lack of working water sprinklers. The fire burned hot enough and long enough to cause the building to weaken and collapse. The report was simply not good enough and was discarded and further investigation was needed. That same year National Institute of Standards and Technology (NIST) came to the conclusion that the result of the collapse was simply the engineering. That was discarded as well.
June 2004The investigation of building 7 was put on hold in 2002 until the initial reports were finished on WTC 1 and 2. In June 2004 the investigation was handed over to National Institute of Standards and Technology (NIST).
June 2007Shyam Sunder explained, "We are proceeding as quickly as possible while rigorously testing and evaluating a wide range of scenarios to reach the most definitive conclusion possible. The 7 WTC investigation is in some respects just as challenging, if not more so, than the study of the towers. However, the current study does benefit greatly from the significant technological advances achieved and lessons learned from our work on the towers."
August 21, 2008NIST final report included that diesel fuel had nothing to do with it and that the Twin Towers debris did initially start the fires. However, the impact of the Twin Towers fall did not play a role in building 7's collapse. The collapse was a direct cause by the fires that were not extinguished or controlled being the fault of the water pressure in that building and the manual water sprinklers that never went off. In other words, The fires, fueled by office contents, along with the lack of water, were the key reasons for the collapse.
The Other StoryvHere is a link to a website where they believe all of this is bulls**t. That WTC Building 7 was actually a controlled demolition job. The video I added is very interesting.
