Why else do you think they only used this small amount MT?
These particular specimens contained all the information NIST claimed to be looking for:
1) Actual temperatures to which these columns were subject.
2) Temperature variation and burn scars between different points of the same specimen would show to what degree fireproofing was damaged by the airplane strikes
3) Comparing damage patterns found on groups of adjacent columns would reveal the actual failure mode causing collapse initiation.
4) Column buckling, high temperature column "creeping" could have been easily seen and verified.
In addition, NIST and yourselves could have easily quieted "nutty conspiracy theorists" the world over simply by showing us the columns in question and showing that there is no evidence of unexplained foreign chemicals or explosive devices.
Were these specimens available and testable, neither Max Photon, A20 nor anyone would have had a basis for argument. Even Pomeroo could have debunked these people with one simple argument: Here are the columns in question, show me the foul play.
Instead NIST settled for the following approaches:
1) Actual temperatures to which these columns were subject.
They guessed through computer modelling. They then state that they couldn't verify whether the model was accurate because they collected an insufficient number of core and perimeter column samples with which to compare the results.
They also admit that the samples collected do not show temperatures exceeding 250 degrees celsius.
2) Temperature variation and burn scars between different points of the same specimen would show to what degree fireproofing was damaged by the airplane strikes
Again, not having sufficient samples to work with, this was guessed at also

3) Comparing damage patterns found on groups of adjacent columns would reveal the actual failure mode causing collapse initiation.
4) Column buckling, high temperature column "creeping" could have been easily seen and verified.
Column buckling was postulated and the actual buckle points on the actual columns in question were never examined or even discovered. No examples of high temp creeping could be shown in the reports due to a lack of samples.
So when you ask: Why else do you think they only used this small amount MT?
Theories based on an effort to cover up the actual evidence of the cause of collapse initiation do spring to mind.
Honestly, Funk, does the recovery of only 4 of 329 column sections containing the key information that NIST was looking for make sense to you?
325 36 foot long column sections of 329 couldn't be identified? Honestly?
