Did some light reading on WTC7 building yesterday. Reading from some personal accounts of firefighters, it seems super unlikely that the building was purposely dropped.
It seems WTC7 was almost completely evacuated by the fire department before it collapsed. There where not even firefighters inside because a collapse due to fire and structural damage seemed imminent. So they cleared the area for quite a while before the building fell. This does not sound like sabotage.
It all makes for interesting reading.
We'll keep in mind, the firefighters had just seen two impossibilities (1 and 2 collapse)...They were scared all the buildings were going to collapse. Especially 6 and 4... They didn't know what to say or do, just imagine losing so many friends and co-workers at one time in something that has never happened before. Especially when right before they collapsed they were reporting the fires were under control and on their way out.
So all buildings were suspect, I would do the same thing. Plus 6 and 4 were destroyed compared to 7...Though they were afraid of collapse, they did not.
Also, I don't know how fire fighters are in South Africa, what training or qualifications/power they have. Here though, they don't have the power/qualifications or training to make a call on a building. For example, the most recent fire I went to here (4 story condo, concrete base, wood exoskeleton, steel spine), burned for almost 3 days. Firefighters kept everone out, fought the fire from the outside and played the control game while it extinguished itself.
After it was finally out, they had one portion of the structure that the upper 2 stories collapsed, other than that it was "intact"...So at that point, yes first responders kept people (including fire fighters) from entering. However, they had no power to make a call about anything. That is when they called my self and a few others to come make the call. After a few days of investigation, we unfortunately had to make the call of condemning it. It is a tough call you cannot take lightly, excluding you are saying to everyone they aren't getting one piece of their personal belongings back. There was also a possible fatality involved. We attempted a drone search..Well anyways.
The point...That is the way power of command works here. Firefighters fight the fires. They make no calls on anything else
