From page 45 of NIST NCSTAR 1A Notice that the NIST uses the term "negligible support" in reference to steel structure that if it had supplied ANY support at all, would have prevented the falling bit from ever reaching free fall acceleration. The NIST either demonstrates gross incompetence or intent to commit fraud. Pick one..... Anybody who can manage to pull a "C" grade from a SCIENCE 101 class can get this. Why are people on the public payroll allowed to get away with this sort of thing?
