Their concluding thoughts:
“the evidence points overwhelmingly
to the conclusion that all three buildings were destroyed
by controlled demolition. Given the far-reaching implications,
it is morally imperative that this hypothesis be
the subject of a truly scientific and impartial investigation
by responsible authorities.”

I will comment that over the years, many military professionals, architects, firefighters, pilots, and others have come forward and called bullshit on the dominant narrative.

Comments from 34 year Air Force veteran who retired as a full Colonel:
“In my first position paper, titled The Precautionary Principle, [see below] written shortly after the attacks on NYC and the Pentagon, I cautioned readers against a rush to judgment, although the immediate evidence suggested the crime had been an inside job. As the years went by, a virtual mountain of physical evidence was collected by hundreds of highly qualified investigators — evidence sufficient to convince any dedicated Grand Jury that the horrendous events of 9/11 were clearly an inside job. The Precautionary Principle no longer applies. It is time to positively conclude that a well-orchestrated and obviously pre-planned cover-up of the worst mass murder in our country’s history began immediately following the deaths of 3,000 innocent people on September 11, 2001. Nearly nine years later [this was written in 2010] the criminal cover-up continues. Fortunately for our country, our judicial system provides no statute of limitations for treason, first degree murder, and terrorism.”
