I interviewed structural engineer Anders Björkman at the AE911Truth press conference of February 19, 2010. Björkman discusses his objections to the “Progressive Collapse” or “Crush Down” theory of NIST’s Dr. Bazant. Unedited audio.    Shawn Hamilton

Björkman calls Bazant's model of "progressive collapse" the "Pouf! Pouf! Theory"

NIST AND DR. BAZANT - A SIMULTANEOUS FAILURE

INTRODUCTION
The NIST enquiry into the destruction of the WTC towers purported to be an examination of the physical evidence. The final report includes commentary upon much of the physical evidence available from this examination but concentrates upon the time period prior to the onset of the collapse. The report does not go into much detail of the period of the collapse itself but instead relies upon the theoretical work of Dr. Bazant, to argue that once collapse was initiated then total collapse was inevitable.

CONCLUSIONS
Dr. Bazant has stated in his analysis, that his energy ratio would be increased in the event of early failure of the column end connections. This is correct and examination of the debris pile with specific regard for the numbered and identifiable columns from the area in and around the aircraft impact area could have given more precise information from a physical rather than a theoretical source.
