Further on...
"...Dr. Griffin’s argument regarding fireproofing is, therefore, unsupportable. The errors he and his quoted sources make regarding the energy requirements are deceptive and easily refuted."
Except that you don't do it here. You've simply reiterated the NIST conclusions without demonstrating why they would be probable.
"Furthermore, we also expect steel that was heated to have been weakened considerably, and thus would not be expected to survive the collapse intact or with any identifiable marking remaining. It is therefore unsurprising that no such samples were recovered..."
Yet NIST indicates that several pieces from the impact and damage zone were identified....
"...A search through debris will naturally be biased towards intact pieces, and these pieces by definition were exposed to less damage and less heat. "
This is so jaw-droppingly wrong. In a properly conducted investigation, collection of steel would be biased towards that exhibiting strains and failures from abnormal events, not regular pieces that tell nothing of the collapse mechanics. This is elementary. That Mackey is attempting to make such claims should send up huge red flags for any critical reader of this paper.
Moreover, it would not at all be "expected" that stressed steel would lose all of its identifying markers, and this just appears to be a guess on his part. Some would and did survive, as NIST has confirmed. A proper collection of samples to investigate the first-in-history, sequential global collapse by fire of three steel-framed highrises by supposedly different mechanisms would easily debunk this evasive and disingenuous claim. As we know, less than 1% of the WTC steel was saved for investigation.
