The indisputable facts are:
the location of the debris damage [with photographs to confirm]
the data about where the fuel tanks, pumps, pipes, and generators were
the location and progression of the fires in the east half of WTC 7
the photographs that confirm the location of the fires

The "In order for debris to get to the supply pipe...." is opinion.

************************************************** ******

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]

- 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

No debris damage to east 1/3 of south face was reported

************************************************** ******

In order for debris to get to the fuel supply
pipe (located 90' inside the building), it would have to
take out 3 perimeter columns,
bust thru 5 - 5 1/2" steel and concrete floors,
including at least 1 floor support beam per floor,
knock 2 elevators out of their shafts,
thru a wall and into the hallway,
take out a core column,
break thru a concrete masonry wall
and a 6" steel and concrete floor.
[NIST Apx. L pg 3 - 6]

There is NO evidence that this happened.

Smoke from a fuel oil fed fire would be pouring out the hole made by the elevators.


12:10 to 12:15 p.m.
- No fires, heavy dust or smoke were reported as they left floor 8
[NIST Apx. L pg 18]

************************************************** ******

Fires:

There were no diesel fuel fed fires in the east part of WTC 7 where the initial event, that led to the collapse, occurred.


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

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.[/quote]
