... and the rest of his "analysis" falls apart without it. One camera is clearly lower than the other. You can tell that from the apparent position of the exit fireball, which this poser "conveniently" left completely out of his "vertical perspective analysis."
Instead, he takes earlier frames and
resizes both so they have the same vertical size, at least for the distance between the top of the WTC1 building and the bottom of its crash site. He then falsely claims that you can see the top of the building in both (when you can't see it in either because of the smoke, which is clearly seen moving in the videos), and ignores the fact that the antenna tops don't
quite line up. He then runs an arrow up and down to show how well
he resized them to be (almost) the same! (Not only that, but he fraudulently resized the horizontal axis of the image on the left at a different scale than the vertical axis, trying to make the two images look more the same. In fact, the two cameras have different aspect ratios, due to non-square pixels, so the building on the left looks wider when resized to the same height as the one on the right.)
That "analysis" proves exactly nothing about the videos (but it does imply a lot about the "analyst"). That resizing trick masquerading as a "vertical perspective analysis" only works for features that are about the same distance from the cameras. If he had tried that resizing trick with images that included the exit fireball, it wouldn't work: Because the fireball is farther away than the north face of WTC1, it isn't possible to simply resize the images to have the same vertical size between all of the features if the fireball is included,
because the cameras are at different heights.But there is a very simple way to absolutely prove to that: View the two images as a "stereographic pair." Our vision systems are extremely good at detecting very small differences in parallax and interpreting those differences as differences in distance. We see things in 3D because of the distance between our two eyes, and we can make stereographic pairs by taking photos from two cameras separated by some distance, then viewing one image with each eye. In these two videos, the camera for the right video is below and to the right of the left video, so in the images below, I have rotated the two images to make the line between the cameras approximately horizontal. This is a "left-right-left" stereo set which can be viewed two ways: The left image and the center image can be viewed as a "parallel" stereographic pair, i.e. by diverging your eyes as if you are looking at something far away until the two images overlap and converge. The center and right images can be viewed as a "cross-eyed" stereographic pair, i.e. by converging your eyes as if looking at something close until the two images overlap and converge. (Some people find it easier to use this method by first looking at a finger tip that's about a foot in front of your eyes, then moving your finger back and forth until the two images beyond appear to be on top of each other, then switching your focus to the pictures without changing the angle of your eyes. Using either method, it's usually easier to get the photos to "fuse" into a single 3D image if you first try to get the edges of the pictures to converge, rather than looking directly at the details.)
When viewed in 3D like this, we see that the north face of WTC1 is the closest feature, the antenna is slightly farther away, the smoke is trailing away toward WTC2, the face of WTC2 is the farthest away, and the fireball bulges out from that wall. In other words, it's a completely consistent stereographic image,
which is only possible if one camera is below and to the right of the other.
When
properly analyzed for camera position,
all of the videos that appear to show different plane paths can be shown to be the same path seen from different angles.
Not one of the "no-planer" videos claiming to show different paths properly accounts for camera position.
Far beyond any reasonable doubt, what we are seeing in the videos of UA175 crashing into WTC2 is a brutal mass murder. Time and time again, we find that the "no-planers" who make these videos are completely clueless about video analysis, yet they insist they are "proving" something. These videos are just pornography for bullshit addicts.
