Would it be convincing since we saw the fuel explosion displaced to the north? ) There's the Scott Myers shot. http://www.youtube.com/watch?v=X4rrQuq9dFM And the swaying is visible to the naked eye. The tower sways to the right (north) after it's hit by the plane and then comes back. This is consistent with a plane hitting it from the south side. Here's a quick gif to demonstrate: The surrounding buildings remain static. So this has nothing to do with the camera motion. Edited by RasgaSaias, Oct 12 2009, 10:44 PM.

The impact of the aircraft into WTC 2 caused the tower to sway back and forth for almost four minutes. The estimated period of oscillation was found to be nearly equal to the calculated first mode period of the undamaged structure, indicating that the overall lateral stiffness of the tower was not affected appreciably by the impact damage. The maximum deflection at the top of the tower was estimated to be more than 1/3 of the drift resulting from the original design wind loads (about 65 in. in the N–S direction) as calculated from the baseline analysis (see Chapter 4). Since the lateral stiffness of the building before and after impact was essentially the same, it can be concluded that the additional stresses in the columns due to this oscillation were roughly 1/3 of the column stresses resulting from the original design wind loads, assuming linear behavior and assuming that the oscillation mode shape and the static deflected shape under design wind loads were identical. Really very cool gif. Duplication effort proceeds.

The next funny thing to do: capture some VHS of any impact recorded on 9/11 and count the frames. Rosy says these had less frames. I bet that one can split the NTSC frames into fields and get 60 different stages of the approach per second. No, don't do that. There are just 1-5 people who can profit from that work.

I'm already imagining Ace arranging an excuse for this. Saying it was caused by the explosion and a strong pull from an atomic vortex, or whatever fits. However we know the explosion was mostly directed to the north side. So if it was caused by the explosion, the tower should sway in the opposite direction!

This would push the tower to the north, whether that force originated as an airplane crash, or nuclear reactions. The orange-black hydrocarbon fireball has nothing to do with it, such have almost no concussive power. The thing to focus on is the white nuclear explosions, which occur strictly on the south face. It appears to me that the tower begins swaying when the explosion occurs, not when the "plane" hits.

The orange-black hydrocarbon fireball has nothing to do with it, such have almost no concussive power. If it wasn't the airplane crash, then was it an invisible force? Because all the moved dust particles and debris went mainly to the north side. A nuclear reaction, or whatever you'd like to call it, capable of shaking a tower like that, should at least move the concrete dust far away from the south wall into the exterior. That doesn't happen. The momentum was preserved even in the fireball. acebaker The thing to focus on is the white nuclear explosions, which occur strictly on the south face. I swear I've got no idea of what you're talking about Ace. acebaker It appears to me that the tower begins swaying when the explosion occurs, not when the "plane" hits. The tower starts swaying when enough energy is transfered from the plane to the whole structure. That happens specially when most of the plane decelerates completely on the inside. The tower should not start swaying immediately after the nose touches the south wall. That's ridiculous. Edited by RasgaSaias, Oct 5 2009, 03:22 AM.

They happen far too late for us to think it might be an atomized airplane. It's not the "airplane". It's the building exploding. We know nuclear explosions are white, see Nevada nuke tests for example. What happens at the wall of the south tower during your "plane crash" looks a lot like what happens to the whole tower later on: building turning into white dust. A great deal of atomized building material is thrown southward. There must be an equal and opposite force. That would manifest as pushing the building northward. Clear enough?

I really want to see those "white nuclear explosions". Maybe you got a different version with some sort of artifacts because I don't think I ever saw anything resembling what you're describing. acebaker A great deal of atomized building material is thrown southward. There must be an equal and opposite force. That would manifest as pushing the building northward. LOL That's not true Ace. You know the amount of building material thrown southward is scanty. The equal and opposite force would not suffice anything near what we see. On the other hand we have videos and eyewitnesses who support a projectile weighing more than 100 tons hitting the south tower. That would easily originate the swaying. But unfortunately you're still denying yourself the most simple and logical answer because it doesn't fit the scenario you want to be the truth. Edited by RasgaSaias, Oct 5 2009, 06:29 AM.

Posts: 298 Group: Members Member #266 Joined: Aug 2, 2009	acebaker The orange-black hydrocarbon fireball has nothing to do with it, such have almost no concussive power. The thing to focus on is the white nuclear explosions, which occur strictly on the south face. 1) a nuclear explosion would be that bright that the whole south face would be illuminated including all surrounding buildings. The heat would immediately vaporize (not break) the exterior wall. The pressure would have broken all windows around the WTC complex. Some survivors would suffer skin cancer, blindness, loss of hair ... because of the radioactivity. Some witness like Fairbanks would have suffered 3rd degree burnings just due to the heat radiation. The electro magnatic impulse would have destroyed all cameras, radios, computers, chopper electroinics... 2) the fireball was nevertheless there. So at least we have to ask who brought more than 5000gal up there and how was it possible to evaporate a huge cloud because fluid kerosene DO NOT explode. If you now thinking about the possibility that a nuclear explosion evaporated and ignited the fuel then you should think about the consequences of some million degrees and the resulting pressure due to thermal expansion. acebaker There are white explosions, quite separate and distinct from the orange-black ones. They happen far too late for us to think it might be an atomized airplane. Hence, it was also too late to accelerate the tower. Once you noticed the sun was shining approx. in a right angle to the east face then you should consider rotating pieces of debris that reflect the sunlight for short moments into the cameras. In any other moment you won't be able to see these chunks because they would appear gray on gray. Any camera CCD chip would react with a bright white "burnt out" dot because of the limits to handle contrast. Edited by achimspok, Oct 5 2009, 02:02 PM.
