Arus: Look at the video listed below in the "Fire on floor 12" section.
If you want to say that WTC 7 was 'fully involved' go right ahead but most people, after seeing that video, would think you a bit daft.
cloudshiprule: It is OK to compare the collapse of WTC 7 to other buildings that did not have debris damage because the debris damage played no part in the
initiating event
that led to the collapse of WTC 7.
NIST Apx. L pg 36:
"If the initiating event was due to damage to the perimeter moment frame, then it would have started along the south or southwest facade."
"Analysis of the global structure indicates that the structure redistributed loads around the severed and damaged areas."
NIST makes no mention of lateral stress in its Summary, or anywhere else for that matter.
The rest of the
L.3.2 Collapse Initiation Scenarios talks about fires.
*******************************************************
There were no diesel fuel fires or debris damage in the area of the initiating event* that led to the global collapse of WTC 7.

Debris damage:
- Southwest corner damage extended over floors 8 to 18 [NIST Apx. L pg 18]
- Damage starting at roof level....5 to 10 floors....near south west corner [NIST Apx. L pg 18]
- Large debris hole near center of south face around floor 14 [NIST Apx. L pg 18]
[just west of center*]
- South face damage, middle 1/4 - 1/3 width south face, floor 10 to ground [NIST Final 4-5-05 pg 15]
- No heavt debris in lobby area [NIST Apx. L pg 18]
- Damage...of core framing is not known [NIST Apx. L pg 51]
- Only damage to south wall on 9th floor at SW corner [FEMA Ch. 5 pg 20]
-
8th or 9th floor....2 elevator cars ejected into hallway north of elevator shaft, visible portion of south wall was gone....possible damage extended to the west [NIST Apx. L pg 18]
Explosion heard on floor 8

Looking from the south east corner of the south face:
Fire was seen on the 12th floor on the south face;
the face above the fire was covered with smoke [NIST Apx. L pg 24]
[the face below floor 12 was not covered with smoke]
No debris damage to the east 1/3 of the south face was reported
Debris would have to enter between columns 8 and 11 [Spak#] to damage core columns in the area of the initiating event.

Fires:
There were no diesel fuel fed fires in the east half of WTC 7 where the initial event, that led to the collapse, occurred.
FEMA pg 28
[bolding mine]
Fuel oil was distributed through the 5th floor in a double wall pipe.
A portion of the piping was in close proximity to Truss 1
However, there is
no physical, photographic or other evidence to substantiate or refute the discharge of fuel oil from the piping system.
The following is, therefore, a
hypothesis based on potential rather than demonstrated fact.
Assume that the distribution piping system was severed.....
The east generator room was in the north east corner of WTC 7 on the 5th floor.
The supply pipe for the east generator room was north of the wall that is on the north side of the mechanical room, 90' from the south side of the building. [FEMA pg 14 - 15]
If the generators [and the pump feeding fuel oil to them] were running, the louver vents would be open. [FEMA pg 29]

If there was a fire in this room, smoke would be pouring out thru the vents.

Fire on floor 12
Form 11:30 a.m. to 2:30 p.m. it burned west to east across the south side
From 2:00 to 3:00 p.m., the fire progresses north along east side
http://img262.imageshack.us/img262/7555/e40rv.jpg
About 3:00 p.m., it reached the north side, east of center, and spread in both directions

By 4:45 the fire on floor 12 had burned out

Other fires:
11:30 a.m. to 2:30 p.m.: fire on floor 22 on south side
About 12:15 p.m.: Fire on floor 7 at west wall, toward the south side
2:00 to 2:20 p.m.: fire on floor 11 at SE corner, progressing north
Around 3:00 p.m.: fire on floor 7 near middle of north side
Sometime later, fire on floors 8 and 13
Fire on floor 8 eventually burned to NE corner and moved to east face
[NIST Apx. L pg 22 - 26]
********************************************************
The reports of fire to the east part of WTC 7 are not going to change in the final report.
The reports given are clear, the times are accurate enough to track the progression of the fires.
It would behoove you to shut your mouths. Did you ever ask yourself why it's possible for me to have a mature exchange of (radically different) views with some posters here (Ladewig, TAM) but not with you? Do you know what sets you apart? I know
