Why do you care when the report comes out, you won't actually read it.
Are you saying that NIST has not said that fires and damage caused the collapse?
When are you "truthers" going to do some actual research and produce some results. 6 years and nothing is kind of poor.
Thar's right. NIST has NOT said that the normal building fires caused the collapse, it's just a "working hypothesis". [set of assumptions]
I have been doing research and found that there is NO evidence to support debris damage or diesel fuel fires in the AIE.
NIST has acknowledged this to be true in the 12 18 07 report.
That's real research and real results.
In case you missed it:
There were NO diesel fuel fires in or near the area of initiating event that led to the implosion of WTC 7.
FEMA 5-28
[emphasis mine]
"Fuel oil was distributed through the 5th floor in a double-wall iron 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 and discharged up to 75 gpm onto the 5th floor in the vicinity of Truss 1."
FEMA 5-29
Although
there is no physical evidence available, this hypothesis assumes that it is possible that both the inner and outer pipes were severed

"One possibility being considered in the NIST working hypothesis....impact......may have resulted in fractures in the fuel piping system..........at the valve box would release fuel under pressure that, if ignited,......."
[pipes would have fractured at the south west generator room where the damage was, not the north east generator room at the opposite end of the building]
Pg 180 [11 on pg counter]
"valve box......near generator #1"
Pg 181
"very near column #79"
i.e. in the NE generator room.
[FEMA 5-14]
The north east generator room was in the NE corner of WTC 7 on the 5th floor.
The supply pipe for the generator room was north of the core area, 90 feet from the south side of the building.
All the other diesel tanks, pumps, supply pipes and generators were in the west half of WTC 7.
[FEMA 5-29]
If the generators were running and the intake/cooling fans were on, the louver vents would be open.

If there was a fire in this room, smoke would be pouring out through the cooling air exhaust vents.
If the louvers were closed, a fire would not have sufficient oxygen to burn hot enough to be a factor in the collapse.
The whole thing about fuel oil [diesel] causing Truss 1 to fail is an ASSUMPTION based on nothing!
FEMA 5-31
"Although the total diesel fuel on the premises contained massive potential energy, the best hypothesis has only a low probability of occurrence."
In addition, NIST knew there were no fires in the north east generator room [floor 5].
NIST L-22
From 11:30 a.m. to 2:30 p.m.:
• No diesel smells reported from the exterior, stairwells, or lobby areas
• No signs of fire or smoke were reported below the 6th Floor from the exterior, stairwells or lobby areas
NIST L-26 [sometime after 3]
• The fire on Floor 8 continued to move east on the north face, eventually reaching the northeast corner and moving to the east face.
Around 4:45 p.m.
Floor 12 was burned out by this time.
[no fire on floor 5 reported]
Yet they list it in their summary.
NIST L-51
2. Fires were observed after the collapse of WTC 1. Fires were observed after 2 pm on Floors 7, 8, 9, 11, 12, and 13. Fires were not observed on Floor 5, but this may be due to the lack of windows. The presence of a fuel distribution system and the possibility of damage at the south face from WTC 1 debris impact, indicates that fires may have been present on Floor 5.
The debris impact might have caused a fire in the SW generator room but not the NE generator room.
The possibility of diesel fuel fires in or near the NE generator room had been investigated and there is no evidence to support this hypothesis.
The evidence points the other way.
There was NO probability of diesel fuel fires in that area.

********************************************
The damage to the south west part of WTC 7 did not weaken or have a significant effect on the area of the initiating event.
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. Progression of column failure to
adjacent columns would have been arrested by the vierendeel of the perimeter moment frame which could span across a sizeable opening due to the strength and stiffness of the frame,"
The report then talks about possible damage to core columns and fires in the area of the
initiating event.
pg 37
" I2.1 South facade damaged
> I3.1 Perimeter moment frame redistributes loads around damage
> I4.1 Local failure only"
PG 41
"If a group of perimeter columns failed, the perimeter framing above this area would have redistributed its loads, due to the redundancy of the moment frame."
pg 42
" Initiating event scenarios from I4.4 to I4.6
> V1.1 Any perimeter column fails
> V2.1 Collapse does not progress vertically"
The report makes no further mention of the damage to the south face.
They site core damage and fires as the possible causes of the initiating event.
