As a qualified engineer who works in the field of failure analysis
and prediction I suspect I am far more knowledgeable and
qualified in this field than either you or Professor Jones and I
have read the investigation reports and failure analyses.

The towers collapsed due to the failure of the struts linking
the damaged inner and outer cores. The outer shell failed in buckling
with a resultant progressive collapse , the floors above
the point of failure acting as a gigantic hammer overloading
each floor in turn

The weakness of struts in a fire is well understood by firemen,
those I have spoken to have a saying 'never trust a truss'

As lightweight steel structures they heat up fast and fail
relatively quickly compared with heavier steel joists.

Keith, you're a qualified engineer. Please give your professional opinion
on these excerpts from Jones' paper (be sure to watch the video links too):


Why do you bother? As "truth" and your other names you asked exactly
the same questions and then called all the responders names,became
vulgar, told them they were wrong, that they had provided "no scientific
proof" and then threw a tantrum before leaving.

As near as I can see the only things you seem to have learned a
jetliners don't fly on diesel fuel and squibs aren't puffs of smoke. I'm
glad I was able to teach you that much.
