9/11 Weekend - New hypothesis to Explain 9/11 - Part I

[Jeffrey Orling]

BY the way... what do you think it would sound like if some huge mass came crashing down hitting one floor after the next? boom boom boom boom? No? If not what would it sound like?

Weren't the "booms" noted before the collapse of 7 began?

So too the large single explosion captured on tape?

I don't know the precise timing so I can only guess. The collapse of 7 was preceded by a 1 minute period where the tower swayed back and forth slowly in an east west direction. This was not able to be seen by the naked eye but was measured by analysis of the video. Buildings don't move like that unless part of their structure is not working and carrying the loads to bedrock. Think of someone on your left handing you a huge stack of books. The additional weight will be transferred down your spine to your left leg... asymmetrical load... and you will actually tip a bit to favor your left leg. Most likely you will move the load toward your center to distribute the load evenly to both feet. If this was captured on video a swaying motion would be evident.

Since there was no new loads added to the tower... there was instead an asymmetrical LOSS of some of the loads paths...(columns or transfer trusses) and so loads were moving to remaining load paths. This would be analogous to lifting one leg from the floor and all the weight is then being carried by your remaining leg. Again you would show some swaying movement unless you are a trained dancer who has very strong muscles and excellent balance.

The beginning of the collapse was an *unloading* of an area of axial load support... likely at transfer truss 3 which carried the column 79 line of 40 stories. Loss of one column line or damage to the truss supporting it was not sufficient damage for the tower to collapse. The column 79 loads were then transferred to other columns or axial load paths and the building *swayed* on its legs so to speak. The collapse of line 79 COULD HAVE BEEN heard as a series of boom boom booms as each column in the stack hit ground or the slabs connected to column 79 on each floor collapsed onto the one below. I don't know... I don't have a crystal ball. But the building was now BEGINNING to fail ... its structure unloading to few and fewer axial load paths.

The east penthouse above 79 dropped down right through the entire tower. The rest of the building stood around this 47 story hole around column 79... then the west penthouse dropped as well to the ground inside gutting the rest of the core. Then the roof line of tower begins to accelerate downward from 0 mph to about 15 mph in 2.25 seconds.. FF. There was nothing below for 8 stories.... most likely the first 8 stories which lost the column 79 line and apparently the rest of the 24 core columns which supported the west penthouse.

The core of course provided about 40% of the support for the floors outside the core and had very few floor loads inside it.. mostly shafts and a few stairs and bathroom. Absent the core side support the perimeter columns were left to carry the floors from the outside of the trapezoid shaped donuts. When the structure failed at floors 6&7 it possibly pulled in the structure at the perimeter of the building from floors 1-7. Above floor 7 the east side had a line of 15 columns evenly spaced. At floor 7 that changed to 7! the East side from flrs 1-7 was yet another truss structure... and it was laterally supported and *tied to* transfer truss 3 which carried the column 79 line. It's possible that the failure of TT3 caused the east side to be pulled inward. A similar bizarre structural condition existed on the west side to the north of the column line. There it had to span over the sub station and so again there were fewer column below 8 then above and bizarre truss structures to carry / transfer the loads of the columns which did not carry down to bedrock.

So the sounds of collapse could be heard BEFORE the naked eye perception of the collapse... and experience as a series of booms at parts inside were coming loose and crashing into one another.

Could the sounds be that of bombs?

If the bombs were placed in the tt3 region to break part of the truss the visuals would be as we saw... a progressive unloading as redistribution of the loads.. swaying and so forth. I don't know how large the bomb would have had to have been or how loud the sound was. My guess is that the bomb to destroy the steel in one fell swoop would have been so massive an explosion that it would have destroyed much more than a one part of the t-truss. It seems intuitively unlikely to have a *surgical* bomb destruction which would produce the visuals. But I don't know about bombs.

How large is a bomb which would sound as we heard? Could it have been something else exploding... such as a transformer... actually caused from over heating of the cooling oil which turned to gas and exploded but was not the cause of the collapse but a victim of the same cause? Who knows?

The collapse seen could have been caused by a placed cutter or heat devise which eroded the strength of a truss chord, panel or failed a connection. This would be silent and no percussive sound from the device would be heard.

So were the suggested devices silent cutter/heat types which produced the visuals... or were they percussive bombs which seem less likely to have produced the visuals? My hunch is that the sounds heard were the structure coming apart just prior to the collapse itself... not bombs.

The motion tells the story.
