Larry,

I’ll have to weigh in with kenc, Dogs and Greg. Not sure where those Architects and Engineers for 911 Truth are coming from but the issue is not about "melting" the steel. Dogs correctly identified the issue. As an architect myself, I can add that structural steel is required to be thermally protected  from heat (by fire, etc) per the building codes and while I’m sure it was just before the planes struck, I doubt much remained on any of the members after the impact. Then the exposed steel would not have had a chance in hell (no pun intended) of resisting the heat from the fuel and once it lost strength, down it came.

What about the support beams?  I can understand the building(s) collapsing but not the support beams unless there was some serious melting going on, down-under, where the planes did not crash.

Video removed by the user!

Three other points against official theory:

– towers collapsing at near free fall speed – as an engineer speaking in this documentary has pointed out since structure should not have been damaged below the impact zone it should have slowed the collapse down – but it was not observed.

– towers collapsing precisely onto themselves – it is possible the steel beams within the impact zone did loose structural strength because of fire even if they didn’t melt – however, it is very hard to believe that fires burning more or less randomly would have reduced the steel’s strength uniformly all over the affected floors. Furthermore, structurally the building should have been weakened more on the side of the impact. Therefore it is really surprising that the part of the building above the fire zone didn’t tilt over but nicely collapsed vertically.

– WTC7 – no plane hit, no jet fuel, reportedly some fires (how they did start?), no structural link to the towers – yet it collapses exactly as the towers.

I’m sorry if I offended anyone with my video post #213 about the secondary explosions at the WTC.  I would take it back if I could and I am not implying in any way that I know the "truth of 911" – I don’t.  My interest is mostly esoteric in that I am active in the engineering community responsible for the "built" habitat – large commercial buildings.  I served as an AHSRAE (Association of Heating, Refrigeration and Ventilation Engineers) Chapter President and have been very active in the society and the codification process for more years than I care to remember. 

My interests in this subject are better served in other venues – I won’t bring it up again unless there is something truly concrete and meaningful to this group.

In these depressing times it is easier to do nothing.  Watch this video "We the People"  http://www.youtube.com/watch?v=jeYscnFpEyA

 You’ll be inspired to action.

Thank you Greg!!!  Haven’t seen you on here much lately but this video is what I’ve been looking for….I’m heading to their site right now.

 

Best!!!!!!
