Ever heard of the magazine "Popular Mechanics"?
You should check it out.
Shouldn't the NIST be aware of such simple stuff?

Yes, thats why its in the report. You should read the report one time, some really neat stuff in there.
Yeah, they admit in THREE PLACES that the distribution of weight is important ot analyzing the impacts and then they don't do it.
But they put that in a sub-report about analyzing suspended ceilings. But the only witness I ever heard talk about the ceiling falling was in the basement. That is pretty damn curious.

Did you actually read the report?

Why? Considering everything people who were in the buildings that day went through I would be suprised if it was of any concern to anyone.
If a piece of ceiling comes down and hits you in the head you probably are not going to forget it.
But I have run cabling through suspended ceilings often enough to know that pieces could hit people without doing much damage.
I have admitted many times that I have not read all 10,000 pages. I have probably never read more than 20 pages in sequence. But with all of the different searches I have done on various words and phrases I may have read as many as 400 pages total.

Yes, you're right. If that's the only thing that happens to you that day at the office. But in consideration of the events of that day, if a chunk of ceiling panel tapped your head as you were running for the exit and then watched 1000's of persons die in building collapse, I don't think its going to make the list.

This.
As someone who has been in a life-and-death situation, I found it surprising which details stuck with me.edit on 8-7-2011 by roboe because: clarification
My point was that THE ONLY PERSON that I have seen say anything about stuff falling from the ceiling was IN THE BASEMENT.
He managed to not forget with all of the other stuff going on.

So why did the NIST produce this report?
NIST NCSTAR 1-5D
Federal Building and Fire Safety Investigation of the
World Trade Center Disaster
Reaction of Ceiling Tile Systems to Shocks
I haven't found anything in it reporting ceiling components falling in the WTC. But they do EARTHQUAKE TESTS.
The only witness I have seen talking about stuff falling from the ceiling was in the basement.
I guess they had to do something to bill $20,000,000 for.

Well, if your read the report it says in there that occupants report falling ceiling tiles, just because you could only find one thing on the internet doesn't mean anything. The purpose of the report was to determine what it would take to knock the tiles loose or down, outside of the impact zone. The ceiling tiles are part of the fire rating system and when they're not in place the fire rating is reduced. What's the mystery? Perfectly legitimate line of inquiry and I doubt if consumed all $20,000,000.
The Structural Engineering and Earthquake Simulation Laboratory (SEESL) staff of the State University
of New York at Buffalo performed the ceiling tile system tests. Mark Pitman, Technical Services
Manager, and Scot Weinreber, Laboratory Assistant, played pivotal roles in the development and
execution of these tests, and their support is gratefully acknowledged.
Armstrong World Industries (AWI) supplied the ceiling tile systems to SEESL. Thomas Fritz of AWI
provided significant contributions to the project, including information on the ceiling tile systems
installed in the World Trade Center buildings. Steven Newcomer and Barry Buhay of the Armstrong
Building Products Installation School did the lion’s share of the work in installing and repairing the
systems during the tests.
Occupants of WHAT?
This is what the report says:
Where in the report does it say that an occupant of the WTC saw tiles falling from the ceilings in the towers?

Page xxix, paragraph three, fist sentence.
Occupants of the towers reported that the impact of the airplanes resulted in some dislodging of ceiling
tiles and damage to the suspension system, but descriptions of the magnitude and spatial extent of the
damage were neither quantitative nor comprehensive. Thus, additional information was needed in order
to estimate where the ceiling system was intact and where the heat from the fires might have impinged
unabated on the floor joist assemblies.
