As always you post half-truths and outright febrications because the whole truth just doesn't support your conclusions:
Did investigators consider the possibility that an explosion caused or contributed to the collapse of WTC 7? This is from a 9/11 "truther" web site:
Yes, this possibility was investigated carefully.
NIST concluded that blast events inside the building did not occur and found no evidence supporting the existence of a blast event.
In addition, no blast sounds were heard on the audio tracks of video recordings during the collapse of WTC 7 or reported by witnesses. According to calculations by the investigation team, the
smallest blast capable of failing the building’s critical column would have resulted in a sound level of 130 decibels (dB) to 140 dB at a distance of at least half a mile, if unobstructed by surrounding buildings. This sound level is consistent with a gunshot blast, standing next to a jet plane engine, and
more than 10 times louder than being in front of the speakers at a rock concert.

In other words, everyone in the building and everyone in the hood would have heard it.
You're a liar, Princess, proven once again and we both know why.
