I have seen the Discovery Channel special on the Loizeaux family.
They show how they developed the fine art of building implosion.
The principle is dirt simple. As Jowenko said, you just blow the support columns [in the proper places and in the proper sequence] and let gravity do the rest.
If you say that WTC 7 does not look like a CD, then it is you who doesn't have a clue how buildings are imploded.
No.
The columns are also pre-weakened with torches. Jowenko mentions that several times.
They are also stripped of cladding and fireproofing.
Complex calculations of load are made and the charges/sequence of firing is geared around these calculations.
Now -
and this is your big problem -
1) If this was set up
before 9/11 then the perpetrators would need to know *in advance* that WTC1 would rain debris on WTC7 and that fires would ensue. Otherwise, there would be no plausible reason for WTC7 to fall. The CD would result in the spontaneous collapse of an undamaged building which would, obviously, not be a workable scheme.
2) i) If it was organised on 9/11 itself - in a damaged and fire-ridden building - the CD team would have to operate around firefighters, police etc etc, in a chaos of smoke and debris. Then they would need - uniquely - to mask the flashes and blasts typical of CD. Under the most difficult circumstances ever experienced by a CD team.
2) ii) If it was organised on 9/11 itself - the CD team would have to be ready to go *in advance*, even though there could be absolutely no guarantee that WTC1 would produce enough damage to "cover" for the CD.
In summary - there is no narrative that makes
any sense whatsoever to explain a CD operation on WTC7. None. Whatsoever.
And don't even get started on
motive, because there isn't one that makes a grain of sense.
So - it looks like a bit like a duck, but actually it's a duck-billed platypus.
