I've made this point to him before too, but he ignores it. Sounds like you've read the NIST report ( he hasn't / won't ).
Sounds like JSO has a pet theory - diesel fires and failure at floor 5 - and won't listen to nor even address the challenges he receives. Just plows on, ignoring relevant counterpoints.
Just like a troofer....
Hahahhahahaahhaahaha
You weren't there Butz and apparently there are images of thick black smoke pouring from the east side of the tower below flr 8... maybe you can explain this?
My "pet theory" is very similar to what FEMA proposed and what the building's engineer Cantor seemed to think plausible and even the ARUP study considered failures of the 2 east side transfer trusses.
And there was no accounting for all the diesel fuel. If there was...an "accounting" perhaps you could provide a link which has some detail as to when it was recovered... how it was recovered and how much was recovered.
Or maybe you want to explain in some detail how the collapse of a few floor sections east of girder 79-44 led to the progressive collapse westward through the building causing the WPH to collapse and then causing the exterior moment frame to rotate clockwise while falling and develop a vertical kink in it aligned with the E columns of the first floor?
I don't have a problem with discussion and disagreements. But without real hard evidence all the explanations are "pet theories".
BTW... what do you suppose would have happened to the building if the day tanks or the supply pipping ruptured and were spewing diesel which ignited and was burning all day?
What is YOUR favorite pet theory?
