Wtc7 Southwestern Area, Source of smoke? Options

(IMG:http://i1067.photobucket.com/albums/u422/cademartatu/d33f23aa.jpg) Maybe there was a north way out?

[onesliceshort]

Well, there was an entrance beside the shipping ramp

The northern door.....(beside ramp) provided access to an exterior store room behind the wall, while the southern door accessed a stairwell that connected to the first four floors.

And this is the description given for the east and west stairways (whether it's reality or not is another matter!)

Stairwell B (also referred to as the east stairwell), located slightly east of the geometric center of the building, was vertically continuous from the 47th floor down to the 23rd floor, where there was a horizontal transfer corridor. The transfer allowed use of the floor space above the easternmost elevator lobby and the elevator machinery on the 22nd floor for the elevators below. From there, the stairwell continued down to the 5th floor, where a second transfer corridor led south and east to the third leg of the stairwell (Figure 7–1), which ran from the 5th floor to the 1st floor, where the stair exited the building through the east wall to West Broadway (Figure 7–2). There were also two secondary exits located off the 3rd floor lobby, leading south over Vesey Street to the Promenade and pedestrian bridge shown in Figure 7–3 and exits from the 1st floor lobby onto Vesey Street. 

And the elevators

--------------------------------------------------------------------------

And I changed the question in my last post. I should have asked if anybody can see a recurring theme that runs through the west facade. The floors above the lower floors "atrium" we were discussing on the northwest area are either blank, have a sparsed out beam structure or designated as "storage areas" or "data centers". Then we have the east face that the owners and tenants are playing dumb with.

I've more schematic images to post.

The elevator core is part of the solution.

They also served as “Wet” columns for the plumbing.

If I were a bad guy…that is where I would be.

Here are those schematics

This is interesting - The Perimeter Hot Water Radiant Heaters and the Make-up Air Shaft.

The entire building is encircled in these and they would have ran the entire length of the building.

This would give you a delivery system for fuel/gas to blow up the buildings. Wouldn't of a leave much trace either.

[SanderO]

Twin towers has perimeter radiation as well... Where is the evidence that the facade (columns) were blown up.. Didn't we see the facade come down almost intact with nothing exploding or even breaking the glass?

You need to link the observed motion to a cause...

[onesliceshort]

They also had claimed that the "smoke purge ductwork" was more than likely "out of operation" because it was controlled from the lobby. Wouldn't this have had an automatic setting too?

NIST also claimed that they would point out where the smoke would be pumped out by this system on each floor but I couldn't find them. I see the "purge shaft" but where did it lead to? The facades? The roof?

On the northeast and northwest corners in the last hour or so there was black smoke billowing up through the curtain wall (which became thick white smoke on the east face) yet the curtain wall was allegedly fireproofed to prevent both fire and smoke from spreading from floor to floor.

What on gods earth are you talking about?

Please be specific.

We are talking about WTC7...

elreb,

For a long time I've been of the belief that thermobaric ie fuel/air weapons were used to destroy these buildings. Not necessarily conventional bombs, but that key areas of the buildings, such as the elevator shafts were filled with gas and then ignited in order to blow up the buildings from the inside out. I also believe that existing mechanical systems were re-purposed on 9/11 to do the deed, thereby eliminating the need to install cutting charges and other explosives that someone might accidentally stumble across before the day of the attack. After seeing the plans you just posted that show the steam and make up air systems that surrounded the entire perimeter of the building, couldn't these system also deliver something more volatile like natural gas or propane (that could be stored in those fuel storage tanks that were all over the 5th floor), that could then be deliberately ignited at just the right moment?

Not likely... propane is very explosive and would have easily ignited uncontrollable... it's also heavier than air and would have to be pressurized to fill... ducts which have lots of openings and electric dampers SPARKS.

[onesliceshort]

What is that "blank" section just to the right of the core where the stairway is?

The same feature can be seen from Floor 7

http://img4.imageshack.us/img4/1468/imagefwxz.jpg

Through to Floor 13

http://img535.imageshack.us/img535/1817/imagevrc.jpg

And more than likely runs through the building to the upper floors(?)

Ah, here comes Johnny on the Spot with the debunk.

I'm sure Hauer ran those pressurized gas lines all over the 5th Floor because he had nothing better to do.

The 5th Floor was the bomb.

[elreb]

FYI
The 4th floor kitchen had a 4” natural gas main feed off a 6” line in Con-Ed.

We never hear about this line!

[SanderO]

The *blanks space* on each floor adjacent to the core was likely mechanical equipment bathrooms and riser shafts.

And didn't they want to run a line through the elevators?

I've been watching this video lately.



East Penthouse:

http://i1067.photobucket.com/albums/u422/c...tu/2f4b885b.jpg

The East Penthouse just fell through the building. Literally fell. Fell through those "anonymous" multiple floors on the east face. The coup de grace when the rest of the building went looked like the legs were kicked out from underneath it. More than likely those atriums on the lower floors. And the northwest face looks like it was pushed out and away (as well as the northeast face?).

My 2cents.

Here's Floor 7 (office space) which show the same area

Hauer wanted to do, but that was going too far for even FDNY. He ran the line through another 'shaft' in the core.

WTF? What doe the grid represent? The ceiling for the open space below? Looks like only one door in.

Any idea what happens there on 8?
