We can only agree on it if it was actually hit by it. the sillouhuette of a plane head on is very small, The area directly hit by it was severely damaged, but those that were not, no damage. Simple. Direct. |

Whats really disgusting, is that these lies and fabrications are being used against us by the enemies of the US to convince people that the US killed 3000 of its own people just to frame musslims. I expect terrorists and others who think of themselves as enemies of our country to lie. What I don't expect is for people in this country to help them by creating false yet plausable sounding theories for enemies of this country to use for their own agendas. Will, just how does it feel being one of the tools used against the US? |
ustwo you need to self reflect. you have to understand that you sound as crazy to us as we do to you. you think torture is fine, we think your crazy; we think our government is ruthless, and possibly used the WTC attack as this administration's reichstag to incite a war and gain control, you think we're crazy.
i am very open to the idea of us being wrong, in fact i welcome it. i would like to believe that these arguments were only coincidental. but no one has been able to give an explaination for the holes in the facts. until those facts are legitimately rebuked i remain a loyal skeptic. |
They should release more video, absolutely, the government is way too restrictive on the information on the grounds of national security.
If you hit a normal brick and mortar building with a plane, the building will be smashed to bits, however, this building was designed to take an attack and survive, and it’s the military HQ for the United States of America, not some 2 bit radio shack. I really don’t see what is so hard to understand. It did what it’s designed to do, survive an attack. Quote:

sorry, i was in a bad mood when i posted that, dilbert.
the commision report stated that several dozen support columns were knocked out. unless i have mistaken the pictures, i am at a loss as to how that could be factual. |
Yes dozens of columns were knocked out, but not in the front, the wings disintegrated virtually instantly after hitting (and went inside a bit) but the center of the plane did nock down support columns in its path deeper inside

Quote:
Cynthetiq is saying there is a margin of error on the estimated path and the actual path, since we know where about the plane hit, we know about where it was going, however the plane could have theoretically been anywhere with in 5 to 20 feet (estimates pulled from arse, bottom line it is just an estimate, some where near the value given). A plane hitting a building is not as simple as a bullet hitting a paper target, on paper, you can see exactly where it hit, with a margin of error of less than a mm, when larger, malleable objects are involved, the error becomes larger, if the estimated path was off by a few inches, the window would have been missed, hell, the people estimating the path of the engine may be wrong, did they properly calculate the torque force applied by the deceleration of the plane as compared to the engine, since it was still attached, there would be one hell of a torsion force. Ustwo, wonderful quote, I like how they truncate Quote:

The Pentagon "evidence" looks planted, where are both engines? They didn't burn up in the fire. How did some stuff vaporize yet other stuff is intact. What made that fairly big exit hole deep in the building... the schrapnel put there doesn't appear to have.
For what reason would the hotel and gas station tapes need to be seized right away? Why can't they be played? What about cell company records showing the calls were made? Why don't any Arabs appear with the passengers boarding the planes? How is it that the government is certain of their identities within hours? Why haven't those been ammended when some turned up alive? |
A cruise missile could not account for the light poll damage, the damaged generator, and many other parts of the damage caused.

I've stated that the estimated flight path is just that, estimated. While they can do simulations on computers and theoretical discussions, it doesn't change the reality of the scene itself. Damage was done over a wider area than what would be for a flightpath of a cruise missle. The hole is too small, yet when I look at the gaping hole in the WTC it seems too small also. IMO that's my own mind trying to "understand" and wrap itself around the idea that a plane hit the building. I've witnessed a plane crash into a house, small 4-5 seater. House didn't look like anything hit it, but it was totally engulfed in flames. I know a plane hit it but there was little evidence of a plane hitting it and leaving a gaping hole. It was also damned hot standing across the street about 40 yards away. I visited the house again after they put out the fire and if I told someone that a plane hit it they would have called me a liar because there was no circumstantial evidence that ANYTHING hit it. It just looked like it was destroyed by a fire. |

Much of the damage you see is due to a few things: 1) the hole This was punched inward, and was done so by an airborn projectile. The hole was approximately 18' across. 2) the outer walls Burned by fires, some windows broken outwards, probably by the explosion. 3) the inside Don't know. There are almot no pictures of the inside, and they are hard to make conclusions from. 4) the inner hole Created by the nose of the plane in the original report, then said to be the landing gear by Popular Mechanics. The firefighters and opther rescue workers have said they found no evidence of plane debris. That suggests that there wasn't a huge arm and wheel (rim) from an airplane, as that would be pretty obvious. It has also been suggested that the hole could have been created by a backhoe to gain access to fires. That ascertion does not prove or disprove either side of this, but if it's true it should be taken into account to get the whole picture. Quote:

as far as the WTC footprints of the planes, different materials and strengths of those materials.
as far as the computer monitor melting? No because there were trees and other items just feet from the fire that raged within the confined space. If I were to compare them then the trees would have had to catch fire as well. |

The right engine stuck both a light pole on the road, and the generator outside of the pentagon. There are too many additional forces to calculate exactly where the engine would go, and just because it missed the window does not mean the plane does not exist. If you were unaware, the generator was the cause of the huge explosion seen on the video at the impact, not just the airplane, it’s the generator. Please watch the video in the article I posted a few times ago: http://www.pentagonresearch.com/lamps.html Further more, here is a new video I found of an f4 fighter slamming into a reinforced concrete wall at 500 mph, the wall is designed to move back to absorbed some of the forces, if it had not the plane and wall would have suffered more damage: http://www.whatreallyhappened.com/IM...er_impact2.wmv When a light aluminum plane hits a solid wall, it gets smashed to bits. |

The f4 plane was crashed into a sample of the nuclear containment building around a nuclear reactor. I wonder how the walls of the pentagon would compare, didn't they make the improvements to that side of the building?
The WTC was a skyscraper and had to be light weight. The pentagon didn't have to worry about weight. But, wouldn't the thousands of gallons of jet fuel exploding and causing a shock wave be enough to break some the windows. In the WTC, the jet fuel went inside, if the wings didn't go into the pentagon, 99% of the fuel would have been burnt on the walls. |

Oh and will the plane hit the ground first, thats why you see no specific engine damage, most of the engine energy would be absorbed by the ground. Took me 5 mins on google to find that and it wasn't searching for your question, just finding how the plane impacted. This is called critical thinking. |

Your argument is like this: you come across a car crash, all mangled up and wrecked and look inside, you notice the rear view mirror is not broken, you conclude that some one staged the crash with a sledge hammer, pliers and a wrench but was sloppy and forgot to break the mirror.

Dilbert, well I guess I was accedentally kinda right about the brick. :thumbsup: As for the engines, I have no reason to think that the engines were anywhere but on the planes when it hit, therefore it is reasonable to assume that they hit the Pentagon, and it's reasonable to try and figure out where they hit based on the location of the hole the fuseloge supposedly made. http://usaattacked.com/pentagon.htm Interesting site. I'm still confused as to how the nose of the plane went theough rings, E, D, and C, or 144" of wall (24" x 6), but the engines did not. Also, the plane did not gouge a hole 100' wide, It poked a hole about 14' wide, then the roof collapsed. I'm not sure how reliable that site is. I'll go look for something too, but I don't know if I should expect to find anything. If you had the plans to a building involved in a terrorist attack, would you release it's strengths and weaknesses? Quote:

Quote:
we have an object about the size of a 757 flying low enough to clip light poles crash into the pentagon, it has to be wide enough to clip the number it did, and not wider otherwise it would have clipped more, the tone the object made changed as it hit one of the poles, a missile would not change the engine tone by hitting an obstacle, only a turbine engine, or possibly a rotary engine, does the missile theory also state that the government faked the sounds with large invisible speakers? Whether or not the plane hit the curb or not is really irrelevant, the impact is the size and shape of an engine, so presumably the engine hit it. Even if it didn’t it still does not matter. So what if the there are some windows that are unbroken, the destruction the pentagon experience was correct for a plane of that size compared to the structure of the pentagon. The windows were 2 inches thick of bullet resistant glass; some would survive a crash. I’m sorry that you feel qualified to predict the exact path of the engine, but you are not, there are way too many variables to say with certainty that it hit the window, no one can, not even a computer simulation, there are to many unknown variables, especially because the engine suffered an impact from a light pole, which did an unknown amount of damage to it, possibly weakening the bolts attaching it to the wing. |

hmm our own government flew planes into the towers by remote control, threw a missile into the pentagon, some how knocked over the light poles in series with out explosives, changed the sound of the missiles engine as it hit one of the light poles, some how hit the generator with out blowing up, then striking the building and blowing up, made 25,000 people in the pentagon lie about it, all the people around the pentagon lie about it, relocated or killed the passengers who were on the flight 77, planted explosives in 3 buildings in new York with out being seen, hit them with planes with out detonating them, then detonating them on command remotely through all the extra debris… Or a group of men, who disliked our policies, hijacked some planes with simple tools, and crashed them into buildings; which collapsed due to a combination of structure loss and fire. Even though its not logical to your mind, does not mean it can’t happen. You seem to think just because you don’t understand something that all of a sudden it’s not true, do you understand friction, gravity, nuclear decay, just cause you don’t get it, does not mean they don’t exist. It’s a big world; you need to learn that there are things you won’t understand but do happen.

Beats the theory of the al Queda instigating the Mt. St. Helens erruption in 1980. :eek:
I think the bottom line is this: There are aspects of the attack that don't add up. Amount of damage inflicted upon the Pentagon seems minimal. Answers and video released by the government are vague and scattered with fallacy. The immedeate melt-down of the WTC remains is strange (to me at least). The passport of one of the terrorist found on the rubble. WTC building 7. Censorship of some footage and commentary on the attacks. Conflicting reports on the elledged phone calls from flight 77. NORAD's three hour response delay. And the way the Bush administration took advantage of this tragic event to promote their own agenda; which is profoundly immoral either way. These things can be explained in many ways, and that's the problem.We cannot agrue to a definitive point for either side until we have more information from the government. Discussion is fine, but I don't see us getting any further without that information. |

All the stock quotes are total bull, they picked and chose the days around 9/11 that had the highest put options, if they knew a thing or 2 about the markets, or the word average, they’d know why. They misuse several quotes; “The speed, the maneuverability, the way he turned, we all thought … all of us experienced air traffic controllers, that it was a military plane.” It should read: "The speed, the maneuverability, the way that he turned, we all thought in the radar room, all of us experienced air traffic controllers, that that was a military plane," says O'Brien. "You don't fly a 757 in that manner. It's unsafe." They left off the part that says it’s possible, but unsafe. But possible. The light poles: They screw this up too. The don’t mention that the light poles on the street are designed to break away, for safety reasons, if a car hits a solid pole, the car will decelerate quickly and kill the people inside, however, if the pole breaks, the car will not decelerate as quickly, sparing the people inside. They say there is no evidence of plane parts at the pentagon, they are flat wrong; here are plenty of pictures of plane parts: http://www.911myths.com/html/757_wreckage.html You know what, this movie is filled with so much half truths, misinformation and flat out lies, It’s not worth my time. |

You actually believe that? "When the first floor failed in the wtc and collapsed, nothing could stop the force the upper part cause by falling, even though it only fell one story, the force is immense. That’s why it fell nearly at a freefall speed" The building didn't fall that way. It just sort of completely crumbled, what made the floors well above the impact disintegrate? "Yeah they took advantage of it, do you blame them? It gave them the opportunity to do what they thought was best for the middle east" Bush wanted to attack Iraq in response, they had nothing to do with the whole affair. Anybody should blame them. At least you are right about the incompetance... and voted them in for another 4 years? |

It did not just ‘suddenly collapse’ as you claim, there were many signs before hand that it was about to giveaway. http://www.representativepress.org/B...plosives2.html As for how it collapsed, the floors above did NOT just crumble the fell down into the lower level, the impacts of hitting the lower level broke the upper floors apart. As for the administrations handling of it, I was not clear with my last post. What they did was despicable, using a tragedy to promote there agenda. How ever, in there eyes the end’s justify the means, they truly believed that Sadam was connected with Al Qaeda and Osama, they thought they knew what was best for the country and took actions to make it happen.

Ptolemy had a very intricate system to show how the planets could still revolve about the earth, since the thought of the earth revolving about the sun was unthinkable. Its amazingly complex, full of laws for each planet, its a masterpiece of mathmatics. It also shows that no matter how wrong an idea is, you can find a way to justify it.
What we have here is a Copernician viewpoint in that the planes caused all the damage of 9/11. Its a solution which works, and while not every fact is known, (Copernicus thought the planets moved in circular orbits), the main idea is 100% correct. Then we have the Ptolemaic view, which is that the most cunning and devious plan in perhaps of all time was carried out under the noses of millions of people, executed flawlessly, and perfect enough to fool every qualified investigator. Much like a 1400 century man who can't give up a geocentric world view, the 9/11 conspiracy type can not accept that their world view was in error and they invent their own types of retrograde motions to complicate the most basic of events. |
I don't think anybody had to endure 1500 degree temperatures. Fire is just not that hot. Ever been near a wood stove, a campfire or a candle? You can stand just inches away from either and not burn up... why is that?
If you believe the witnesses who were just a couple floors above for a while after the impact it wasn't hot enough to mention. The fire would need to be forced and directed (aka: a torch) to have the claimed effects on the building. A whole lot of video evidence shows just what the fire was doing, to compare with other more severe building fires it looks pretty minor. Nothing to make it collapse. Quote:

Your arms move slowly, the air moves very fast. This is because the air is channeled and under pressure.

So you're suggesting I post evidence that fire is not hot? That we can not melt steel with fire? How about I post evidence that fire occurs and is not simply a government conspiracy. Jet fuel burns hot. Mixed with paper, carpet, and all sorts of flamable things inside the building it's going to burn hotter. With a giant hole in the side of the building plenty of air will flow in to feed the fire. With concrete floors that heat energy will be concentrated, and the only thing for it to do is give it's heat to the building itself. Quote:

Were you expecting some sort of movie type "pause" where the failing columns hold out long enough for another group of people can get out of the building?

again, once the structure object under pressure fails, the rest of it is pretty simple.
Regardless of the way it is imploded, the resistance is still the same is it not? A building in demolition is falling at nearly free fall speeds once the structural support is compromised. |

Nothing, and I mean Nothing could stop that many floors from dropping. Quote:

Demo: First thing to go is the bottom supports in the building. -the bottom of the building always has the strongest supports, as it is designed to take the full weight of the building. -removing the bottom supports first ensures that as the building collapses it has little to no resistence from the frame. -immediatally after the bottom of the building loses strength, then the middle and top are destroyed to ensure that the building will not fall anywhere but inside it's footprint. -very few demolitions fall at free fall speeds. Many of them are close, but those are usually smaller. WTC: The collapses started at the upper middle and top, with no structural strength loss at the lower middle or bottom of the building -the strongest supports would still have been intact when the building collapsed, which would offer resistence, but more importantly that would cause the building to be more likely to fall well outside of it's footprint -the building had experienced only moderate fires for a very limited amount of time -it fell at free fall speed, and the WTC are the largest buildings to collapse in history |
are there facts for it being timed at free fall speeds?
what i witnessed did not look much different than the speeds of buildings I've seen implode in Las Vegas. |

I have a physics midterm to study for; I think this is my last post for the day. Quick note to cynthetiq, the speed of collapse was just slightly longer than a freefall. I’ll crunch some numbers to find the experimentally derived resistance the tower experienced to fall in the time it did. |

I don't think it was 1500 F at all. I'm not sure how NIST figures 1832 degrees how did they sample that? |

It may APPEAR similar but that's because from what I understand of physics things fall at the same rate and speed. Once the building structure was compromised, the collapse was similar to me. |
Why are you arguing with someone who couldn't pass physics 101? :rolleyes:
Debate requires a baseline understanding of the issues and you have shown that fastom lacks that understanding many times over. |

BTW, I was reading my other post, and I wasn't trying to be sarcastic, slightly snarky I admit it came out, but was trying to elicit a response as to what your expectation was. |

I guess we just see things differently.
If we both saw a man jump off a bridge we'd probably gasp as we watched him fall. When he started slowing then stopped short of the ground then began to rise up again we'd analyse what we saw. You'd come up with some fancy physics that say his body was in shock which caused him to lose enough weight to slow his fall and his screams made warm air pockets and the inversion lifted him back up. Me, i'd notice the rubber cord around his ankles. |

Fatsom is kinda right. We've been dancing around this the whole time, but he's right. Example? The 1800F temperature is based on the maximum temperatures possible for a fire fueled by jet fuel, desks, chairs, paper, drapes, etc. It almost certianally wasn't that hot. Eyewhitness reports talk about how the fire was dying down as much as 20 minutes before the collapse. Cheif Palmer, on the 78th floor of the South tower (the one that fell fastest, and yet most of the fuel spilled out and exploded outside the building), [I]from the crash zone[/URL], said there were "two isolated pockets of fire" when he called for backup and requested 2 hoses to put them out. Reports like this one come from firefighters that were inside the building putting the fires out, and I'd imagine firefighters know a thing or two about the behavior of fire. Remember, jet fuel burns between 800F and 1500F, which suggests that it's more than posible that they were burning at 800F. They could have been burning at 400F, considering that most of the jet fuel burned off in the initial explosion. Not even Dilbert could make the buiding fall with 800F fires. Even with a 1500F fire, it's a real stretch explaining the collapse of the building. It has to assume most of the fire protection was stripped fom the steel. Some of the fire protection was stripped by the crash itself, of course, but it's not like all the fire protection from the whole floor was lost across several floors. You'd need to have ideal circumstances for a 1500F fire that was consistanly hot to heat the uncovered steel to a temperature where it started to lose any of it's tensile strength. I'll tell you what, let's split the difference and say that the fire burned at 1150F. Add to that the heat from the fires on the desks, chairs, paper, drapes, etc. (even though the temperature of a fire is not a cumulative number based on the emperatures of the individual fires), and we'll say about 1350F. And that 1350F temperature did not last a full hour. It started cold, built up to hot, then dropped off and went down again. Those are hardly the ideal situations that NISA, FEMA, Dilbert, and PopMech suggest. Oh, and if you want proof that PopMech isn't reliable, check out what they are saying about 9/11 cough, a condition that effects thousands of rescue workers and brave civilians who dug through the rubble to find survivors. Yikes. Talk about disrespecting the heros of 9/11. I can't belive that Popular Mechanics can't figure out that pulverized cement in the air is toxic. 70% of 9/11 recovery workers suffer from severe lung problems.

by that same "dancing" I can easily say that the WTC core center structure was hit by a plane that was travelling at 500+MPH and that in and of itself was compromised, the fuel fires themselves just added a small component. The same plane which heavily damaged the Pentagon which is a reinforced building supposedly designed to survive military strikes was able to do as much damage to the WTC which was not designed to withstand such an onslaught.
Isn't that the same kind of thing just different perspective or dancing position? |
