WTC South Tower - Wrong Tower Fell First

[Fintan]

[DeepLogos]

The emotional terror that doesn't wake most people up, but shuts them down... Terrible stuff. A call from the 105th floor of the south tower as the tower begins to collapse... There is no fear that the bulding is going to collapse, it just suddenly collapses. Indeed, the wrong tower fell first. This is the kind of stuff that most people cannot get their head around. Who would do something like this? The emotional barrier is a tough, though understandable, one...

I know this thread is called 'The Wrong Tower Fell First', but I'd like to
broaden it out a little. Doing so may be the key to the collapses.

What we also see is two completely different strikes on each the Towers.

Partly because, unlike the towers, their cores were themselves not square.
They were rectangular. The core in the North Tower ran east-west, and
the core in the South Tower ran north-south.

The first impact --with the North Tower-- was centered on the Tower.
And it came from the north --so the plane hit the core across its full
width. The impact was considerable.

Take a look at the Pallisades seismic reading
for the plane impact with the North Tower.



By comparison, the plane which struck the South Tower, hit it off-center.
And it struck the narrow end of the core with only a glancing blow.

Which produced a much lower seismic reading
for the South Tower plane impact.



Just look at the difference in the two impacts!

By the way, besides the angles the cores were struck at, the other big
difference is that the South Tower was struck much lower --where the
steel was up to twice the strength.

Of course, all this has implications for the mainstream theory.

As the seismic readings show, the North Tower impact was at least twice
as destructive a blow --on a high portion of the tower which had much
less steel to take the impact.

And the North Tower took over twice the fuel load of the South Tower,
once again with higher fire potential on lighter, more damaged steel.

That makes for a good argument that the wrong tower fell first.....

But what's may be even more interesting is the implications of this for
alternative theories of the collapse.

If these strikes were carefully planned military-style operations, then
why are the two strikes so different?

One would think that if the planners had devised a way of downing the
Towers, then they would have executed the same angle of strike at the
same height --in both cases.

It's not like they were in a hurry. That second plane could have come
into the South Tower at the same angle and height as the first.

Even if an angled approach was needed for pyrotechnics, then why not
strike the South Tower higher up and more full on to the core -like the North?

Why two different types of strike? Was the type of damage inflicted
on the towers irrelevant to their imminent collapse? Was there some
other reason?

This may be key to figuring the collapses out.

Now, to play devil's advocate - don't those "see-through" shots of the towers totally disprove the "square concrete core surrounding the columns" scenario?

Even if that's pre-completion, the cores would certainly have to have been completed as they went up.

[Jerry Fletcher]

I don't think so - or I'm not sure what you're getting at.

I see thick rectangular columns running up the middle of the whole thing. They look 'spindly' from a distance, but in perspective to the other buildings and stuff, they're thick.

It appears to me to support Christopher's description of the core, which differs from FEMA in the thick ass concrete blocks in which the steel beams were encased. The concrete was doing as much or more than the steel in supporting the building.



Am I missing something here?
Whatchew talkin bout, Willis?

[Rumpl4skn]

Your diagram shows an all-encompassing, 4-walled box around the entire core.

Unless sun shines through concrete, I think there's a bit of a problem with that.

Don't get me wrong - the C4-rebar concrete scenario makes sense and I'd love to buy it. But then we have to explain those photos with a non-solid core. They don't jibe.

[Fintan]

I think the core schematic in the image above is admittdly oversimplified.

If the photos above were taken before the doorways at the end of
the corridoors were hung --then we would get light coming thru.

But there were clearly lift shafts, stairs, corridoors etc.
And all these did not simply hang in mid air.

Either way, that makes for a lot of concrete & steel in the core.

[Jerry Fletcher]

Ok - I think I see - yeah, that is confusing.

The top of Christopher's diagram is misleading, but I think if you continue the hallway crisscrosses all the way up to the top , and put an elevator shaft down the middle, then then from a distance it looks like four rectangular box columns rather than one thick block.

I think the light is shining through the hallways that ran through the core, or at least thats what the caption said, so maybe that's what I saw. But I think the core, with hallways and elevator shaft looks from a distance like four separate cores, but I think they all function together in supporting the building.

Then again, I've never built a sand castle that's lasted more than 10 minutes and I know zero about actual construction - just so you understand my qualifications for comment.

Maybe I can entice Christopher to explain here in more detail.

I told you those pictures were kewl!

If one is to believe that explosive charges were either built into the structure or put there during its lifetime, I think people would only have to check to see if everything was working properly. This is of course just conjecture, but as I think that the takedown of the towers must have been in the planning for quite some time, it is plausible to assume this. At some time, some kind of explosives must have been put there to account for the explosive nature of the collapse (plus witness accounts). In this regard I am just throwing out a few hypothesis'.

As for the evacuations it is mainly the many reports of evacuations the preceding weekend (powerdown and men in overalls moving into the building) as told by Scott Forbes (YouTube link) of Fiduciary Trust on the 97th floor of the south tower.
(mind you, Fiduciary Trust had scheduled a emergency drill for that day according to the NY Times)

DL -- Thanks for this info. I think we should have a new topic for this and anything else anyone can find - "WTC - Evacuations/Drills/Powerdowns" or something like that. I've posted this in the suggestions thread here.
