There seems to be a bit of a problem with your calcs

I used S=u.t + (a.t^2)/2 which transposes to t=(2.S/a)^0.5 considering initial velocity u is 0.
For S=417m and a= 1g = 9.82m/s^2:

t=9.22 secs for freefall if normal air drag and terminal velocity is ignored

The freefall velocity at impact would be a.t = 90.3m/sec or 202mph and that's the only time the mass becomes a factor IE determining the energy to be dissipated in the impact.

Put it this way....

The Stairways would be blocked by material not normally found in Stairways,
ie: Concrete, Steel, Bombs, Thermite Containers, FBI Agents.

Work with me here.....

So the Concrete, Steel must have come from some where else, Unless the
FBI filled the stairways with Boxes prior the Planes ploughing into the Building.
This would be unlikly as they would have to blockade every level, not knowing
where the Plane was going to Land.
This can only really mean, that concrete and steel is missing from some where
else higher up. This material could be the Floors above, but most likely it
would have belonged to Central Core.

Is this really that hard to comprend or what ?

You with me so far.....

So if Pieces of the Central Core are Missing, then is safe to say that there
must be gaps in the walls holding up the Upper Structure. Therefore it was
just a matter time.

This really isn't a difficult concept, What would happen if you banged a
2 Meter hole in a wall in your house. Is the roof going to stay in exactly the
same place.

The meaning of Dropped is , The act of falling; descent.

I do find it strange that people are so focused on smoke puffs, speed of fall,
the fires, playing videos in slow motion fowards / backwards looking for that
elusive frame, have not seen the tops of the towers collapse first before the floors.
The outside Steel Walls were not moving when the Center Tower
started to fall.

Wait, no - SLOW DOWN. You are grasping at distracting straws so fast that I am actually having trouble "COMPRENDING." I am not even sure how to.

Yes. So far you have danced around my question with lots of pointless words. Keep going.

...and there we go. You did not even come close to addressing the one simple question I asked you with all that rambling. When you pretend to throw a ball, do you rejoice in outsmarting the dog? It is starting to look like you think that you can use that tactic on people too but no.

I asked a simple question. Either answer that or do not bother replying to me.

Is that that hard to "comprend?"

What you are seeing is the internal collapses ahead of the main debris wave - as the section above collapses it slams in the floor below overloading it and causing it to collapse.


Exactly!! I remain amazed that people do not have a rudimentary understanding of how things work. I always thought this was such a simple science, but for many seems hard to grasp.
I saw no flashes, heard no explosions, and as person that has knowledge of general physics, this is how things collapse, and as a result of that collapse, there will be displacement of air and materials that have the appearance of an explosion. Like I said, simple.
I haven't commented on the 9-11 threads before, because I get so frustrated. I mean, you guys know that this whole conspiracy was started in the middle east, accusing the Jews, right?

What do I mean by "Dropped" It fell, it lowered, It sagged, it fell,
no longer supported by the structure beneath, no longer in the same position
it was 5 minutes prior.

Where did it Drop?. Well Down, distance indertimant from Videos

What do you mean by "Bouncing" around?, Like a Super Ball, No
it just Dropped, like there was nothing holding it up any more.

Did it drop down right down through the Earth below?, Through the
Earth, I don't believe that is possible but if it could, it would come out
about 1,000 Km south of Perth, AUS in the southern Ocean.

Where did it drop to, exactly?, I can't tell exactly from the Video.
But you could say it fell 417 Meters to the ground.

Still its impossible for the building to free fall on it's self and hit the ground in 9.22 seconds.

9.22 sec is what it would use if there was no resistance.

That building must have been sucked down by a vacuum. The only thing that could create a vacuum is explosives. Pre installed and going of before the collapse it self.

I would suggest that you take a look at some of the videos on here.

www.pbs.org...

It will show you and explain exactly what happened. There were no pre planned explosions that occurred on 9/11. The sheer magnitude of rigging the building is impossible. The US cannot keep the invasion of Iraq a secret from CNN do you really think they could cover up the years leading up to 9/11? You are giving them way to much credit for planning an executing 9/11. The only thing the government is guilty of is NOT taking those 'guys in a cave' as they are described seriously. We should have ended Al-Qeada after the USS Cole bombing personally.

The 'explosions' are refracted sunlight(but since the speaker in the video tells you there is no light there you are led to believe it) and the expelling of the contents of the floors below that are now crushing the floors below because the main points of support eventually failed.

Now, if they had somehow wired 2 floors I could believe you. Use contractors laying Cat 5 and new firewall gear so no one pays attention to the huge CISCO boxes that go up and down. Then when the plane hits, someone ignites your nano thermite with sound wave or laser triggers. Then, upon impact, the WHOLE thing comes down then. All you would need to do is make sure the pilot hit the correct floor(or the remote pilot).

But load up the ENTIRE WTC 1,2, and 7 with conventional and nano weapons that leave NO trace evidence? I do not think so.

I would make two suggestions to you.

1. Do not get yourself involved in a conversation you obviously have no real intention of engaging in. I asked a simple question of the OS supporters that make a specific claim. Either answer it or move along.

2. Until you can answer the question I have asked you many many times, I would not volunteer to share anything with me.

Your entire post is a bunch of nonsense about explosives, wiring, yadda yadda yadda. Not one bit of that applies to the one simple question I asked. Is there a contest to see who can give the most distracting and off topic answer out there today?

Can't compare the Pentagon to WTC or any other Building, just like
you can't compare the WTC to any other Building.

The Pentagon was a Traditionally Built Building with re-inforcement to
survive traditional Bombs and small aircraft.

The planes were more than superfiscial.
Only a few escaped to the Impact Zone and Above.

Why you might ask

Turns out these Massive building only had 3 Fire Stairwells and were
all located deep inside the Inner Core. All stairways must have been
blocked. For these to have been Blocked more than half the Inner Core
must have been breached. Or they could have escaped but the FBI paid
then a Million Bucks to take a dive.

And if you look a vids, you see the Tower built on top of the Central
Core gave way first, indicating the Core Dropped. The Floors could do
nothing else but follow.

The entire plane went but didn't come out, it had to go somewhere.

It is the Inner Core that holds the Building Up not the Outer Tin Can.






Are you still talking about the South Tower? I thought in the official version of collapse it was only the North Tower who's cause of collapse was said to be the softened core, whereas in the South towers case, it was the perimeter connections that failed. Not that it matters that much, since the original versions omitted fairly important information about the actual structures. David Chandler's video on the South Tower is very revealing in that sequence that shows that there is little left of the collapsing top portion of the Tower, at a point not far below the impact area. It has totally disintegrated. You would think that even the massive hat truss would have been intact, but you just don't see it.

They're not "puffs of smoke". They're ejections of dust and large chunks of debris. And no, there can't be any other explanation for it because those concentrated ejections have only ever been seen in controlled demolitions, period. You will never find them in fire-induced collapses, earthquake collapses, or any other type of collapse that is not a controlled demolition.



Originally posted by skeptic_al

automatically means Explosives were used at the WTC because it also
had a puff of smoke.

No, not automatically. There are other signs of controlled demolition at the WTC like firefighters seeing flashes going up, down and around both towers as they were collapsing, explosions before and during collapse sequence, the near free-fall collapse speed. Every single piece of evidence points to CD and zero to fire.

concussion?

My own conclusion through painstaking research.



Originally posted by skeptic_al
I still can't see how those leaving below the damaged floors can determine how much damage was done (13-15%). And I would think all people on or above the Impact Zone would disagree with that 15% damage.

We're talking about damaged columns. 13% to 15% of the columns in the impact zones were damaged or severed. That leaves 85% of the structure in the impact zones intact.



Originally posted by skeptic_al
And since when has 911 truthers used scientific evidence analysis.

Every day, in fact. Just because you may not understand the science doesn't mean it's not being used.

By the way, 14%-15% is NIST's calculations. 13% is mine.

That is blatant dishonesty.

The WTC is not unique in the least. It wasn't even the first tube-structured building. The DeWitt-Chestnut apartment building in Chicago was the first in 1963. It laid the foundation for other tube structures. And, in fact, most other supertall skyscrapers since the 1960's are tube-structured like the WTC.

I'll say that again in a different paragraph for those that didn't catch it the first time: most other supertall skyscrapers since the 1960's are tube-structured like the WTC.

I guess you have no idea how the core was constructed. There were 47 columns in the core. Obviously there is space between the columns. The walls surrounding the stairwells were not the thickest and most sturdy. Debris from the impacts breached the walls to the stairwells, blocking them. That had nothing to do with how much damage the core sustained or not.



Originally posted by skeptic_al

That's because that's where the explosives would've needed to be and that's what was blown, the core.

Pieces of the central core weren't "missing". Debris from the impacts penetrated the thin walls of the stairwells.



Originally posted by skeptic_al

started to fall.

Again, that's because the core was blown. That was the only way to bring the towers down was to destroy the cores.

You didn't have to. Firefighters saw the flashes and heard the explosions. Survivors, by-standers, first responders, and news reporters all heard the explosions, pre-collapse and during collapse.

I don't know where you think you got that information from, but news anchors and the usenets were all buzzing before dinner on 9/11 with how the WTC had to have been blown with explosives because buildings just don't fall like that.

The south tower would have much more damage due to being hit
significantly faster than the first.

The core would have also taken a big hit.

Why do people think trusses are strong.
Even the Firefighters have a catch phrase for them, Never Trust a Truss.
They just don't have one for I Beams, why do you think that is?

Those terrorists were actually quite smart, they knew exactly how to hit the
Towers to inflict the maximum amount of damage. Any further up and it
might of even survived. I think they made only a couple of errors: they didn't
count on double plexi-glass windows so they couldn't throw their Passports
out the Window, so they would have been holding them high
in the air in the cockpit.They wanted to let the Government know who
was kicking their A**. The Passports was a really big Deal. If all the Passports
were found by Yorkers then the Intent may have been more clear.
And I think they were expecting the Towers to tumble almost
Immediately. They also would have figured out what the Authorities
would do and when. This is just Speculation, but if you think like a Terrorist
it all "Falls" into place and makes sense.

What are you talking about? you are in reply to me, but you talk about something else, it is a waste of precious oxygen. Now, I will ask you a simple question, based on the NIST reports, and all it needs is a simple answer. Did the aircraft "vapourise" the Towers, or did the Towers "vapourise" the planes? all you have to do is bear in mind the NIST report on the planes entering the buildings, and what happened thereafter.

"Vapourize", WTF are you on about.

Who said anything about Vaporizing anything!

And Vopourize means: to convert or be converted into vapor.
To answer both questions then, The aircraft did not Vapourize the Towers, and the Towers did not Vapourize the Planes.
And just in case, you can't use the term Disintergrated either because
that entails transformation at an Atomic level.

So your going to say: where did the planes go then?

Rely to SKEPTIC Al,
Nope,
I asked you to answer the question based on the NIST report, you can Take their South Tower example, in their cartoon the aircraft is shredded, (that's a better word) into little pieces and ends up in a corner, then the alloy ends up on fire and the heat causes the perimeter wall trusses to buckle and the building to bend and so on. That means that the perimeter walls in themselves were enough to shred the aircraft to little pieces, apart from the big bits like the engines that continued through to the outside, though not much talk about them. Compare that to the North Tower where the aircraft went straight in, where the analysis was that the aircraft took out the perimeter columns AND enough of the massive core columns to the extent that again the building was compromised. Do you not see just a little contradiction there?

It doesn't matter if the Plane was sliced,diced, julienned or shredded..
The fact remains that parts of the strairway walls had fallen blocking
the stairs. That again indicates a significant amount of damage was
done to central core.
