Evidence of cutter charges in WTC 7?

FEMA report on WTC 7 collapse

World Trade Center Seven collapsed on September 11, 2001, at 5:20 p.m. There were no known casualties due to this collapse. The performance of WTC 7 is of significant interest because it appears the collapse was due primarily to fire, rather than any impact damage from the collapsing towers. Prior to September 11, 2001, there was little, if any, record of fire-induced collapse of large fire-protected steel buildings...

I was looking at the video of the WTC7 "collapse" and found some interesting things in the pictures. Picture 1 is just when the collapse started...Pictures 2-4 show (highlighted) puffs of smoke coming out of the upper floors. The puffs appear to come out of the columns. My guess is the columns were kind enough to destroy themselves to prevent the building from falling outward towards the building across the street.

The most important and disturbing facts on Building 7 (Questions 5-11 compiled by "ENDIMION"):

1)
Both DoD and CIA had an office in Building 7 on the 25th floor.
http://www.nytimes.com/2001/11/04/national/04INTE.html
http://www.house.gov/science/hot/wtc/wtc-report/WTC_ch5.pdf

On the 26th and 27th floor was the office of Standard Chartered Bank (->).
Due to the official indictment of Zacarias Moussaoui (->), the official 20th hijacker (->), it was a dubai account of Mustafa Ahmed al-Hawsawi from Standard Chartered, which transfered money to Moussaoui.

The FBI has linked Hasawi aka Mustafa Muhmmad Ahmed , via joint credit card accounts, to Khalid Shaikh Mohammed (->), one of the accused masterminds of the Sep11th attack.

As we learned later, another alias of Shaikh Mohammed is Saeed Sheikh (also spelled Shaykh Saiid).
Actually, CNN reported in October 2001, that "investigators have now determined that Saeed and Mustafa Muhammad Ahmad are the same person."
Sources: CNN, 10/6/01, Washington Post, 12/13/01
Saeed was later accused of being one of the killers of Daniel Pearl (->).

2)
There is no official testimony on the collapse on Building 7, only a study, which doesn't come to any single conclusion, why B7 collapsed.
http://www.house.gov/science/hot/wtc/wtc-report/WTC_ch5.pdf
In September 2002, Con Edison therefore decided to sue Building 7.

3)
The former footprints of Building 7 can not be visited by tourists, it's the only side, which was still closed at the end of 2002. Federals watching the outside of the former building.

4)
Blackstone Group, a subsidiary of military company TRW, obtained a mortgage on Building 7 in October 2000.

5)
34 km north of WTC, Lamont-Doherty Earth Observatory of Columbia University registered a 0.6 Richter earthquake at the begining of collapse.
-Isn't it a bit strange to register it 20 km far away? In the beginning of the fall?

6)
The building fell down in an ALMOST PERFECT free fall.
As it was 174 m high it's free fall would be 5.956 s. It fell in 6 s.
That is difference of 0.05 s!
-It is maybe the most promising physical fact that has to be considered!
Simple equation says it.
t= sqrt(2h/g)
And look how it violently starts to sink! Without any tensity or cracking of the facade.

7)
It fell DIRECTLY in its own footprint. The debris was spread only a bit more than 10m around.
The pile of debris was less than 15m high.
Normally, it should TILT and destroy a block, or another building, like Verizon, or US Post Office. It should collapse slowly. And the pile would consist of many big pieces of floors-none found. There were only few "big" pieces of facade maybe 3-4 floors big. Everything else was MUSHED.
It is extremelly dumb to even think that EVERYTHING would be broken. Simple collapses (like when we just sewer the building's foundations) should be pretty caotic (even more for a LOCAL fire).

8)
It was burning (not so vigorously as media says ,I saw the pictures) for 7 hours. Those fires were local, spread on 2 floors.
Not AS CLOSE as the First Interstate Bank in 1988 L.A.
(it's FOUR floors were burning for 18 HOURS! The fires were great).
Someone at other forum mentioned diesel explosions. I ask you: Do you think that diesel fuel (oily and heavy) could EXPLODE and throw of balance a STEEL tower?
I think no. Neither car gas could. Diesel doesn't create so much flamable steam that could get into a proper mix with O2. And there have to be good conditions. Car gas is volatile and it would explode, but NOT with such vigourosity as for example TNT. No way.

9)
It's penthouse sinked first, meaning that the center of the building was destroyed first. I think the center was mushed, then the facade broke down while falling.

10)
Chain squibs are visible going on ~10 floors. Did you see them on your video that you posted a link to?
Again mushing. I wonder sometimes why would the bad guys that did this plant SO MUCH detonators inside-it is useless. There could be less of it.

11)
First steel-framed building in history that fell cause of fires.
