World Trade Center Collapse Investigation Hearing, May 2002 (Pt. 1 of 2)46x61248111519
Initial FEMA WTC collapse investigation failed - http://www.youtube.com/watch?v=iUA5HX_kd6A -- the ASCE was hampered and disallowed access to important info and evidence. By the time the NIST investigation would begin, that steel evidence would largely be gone.
This video: House Science Committee Hearing May 1, 2002, New York Representative Sherwood Boehlert, the Committee Chairman, started by noting what was learned in the hearings two months previous. He said:
"On March sixth, we delved into the procedures that were followed to assess what had caused the towers to collapse in those indelible moments of September eleventh. We were not happy with what we learned. We found that the study of the collapse had been hampered by bureaucratic confusion, hesitation, and delay -- by a lack of investigative tools and by excessive restrictions on the flow of information.
Nothing insured that investigations would begin quickly enough to preserve valuable evidence."
