Five and a half years after the attack and not a single civil (structural, construction or otherwise), mechanical, or materials engineer with a background in construction methods or materials, forensic engineer, fire engineer, demolition expert, construction expert or metallurgist has questioned the collapse theory or NIST's findings. All the conspiracy theorists can point to are a tiny handful of scientists who make claims about things that aren't in their area of expertise or experience. No demo charges were seen or heard at the time of the towers' collapse, no detritus of explosives, detonators, cabling, etc. was found in the rubble, no one saw any bombs or any demo teams installing explosives during the months it would have taken to do so. The conspiracy claims are all based on unsubstantiated assertions, willful misinterpretations, and falsehoods.
