757's are prone to strong influence from ground effect. At the low angle of attack, the plane would have floated above the ground as it came in.
Originally posted by SpittinCobra What ever the plane was, I dont believe it was being operated by a human. If it was going 200-500 MPH, I dont believe a human could get as low as the plane was fast enough to hit it straight, and not hit the ground. [edit on 15-9-2004 by SpittinCobra]
I already covered this in the other thread, but here it is repeated. There's no magic involved, and it's nothing new (it's been in flight text books since 1940). There is a large build up of airpressure under the wings of an aircraft as it gets close to the ground, this force is called ground effect. The faster you are going, the stronger this force is. Model aircraft pilots have been taking advantage of ground effect for years when taking off (you just start to clear the runway, level off not very far above (inside 1 height of 1 wing-length of your craft) the ground and take advantage of the extra lift provided as you acellerate your plane). "When an aircraft enters ground effect during the landing flare, the aircraft may tend to float because the lift-induced drag is reduced quite dramatically as the aircraft descends below one wingspan distance from the ground. Any excess speed at all -- you know, the 10 knots for Ma and the kids -- will cause this float to become excessive. This can cause an inexperienced pilot to grope for the ground and possibly induce pitch oscillations." The pilot of the 757 wasn't trying to land, he was trying to ram the building... The 757 was going over 500mph, 757's normally do 150 KIAS (knotts indicated air speed, or about 172mph) when they land. Aircraft land at slow speeds for a few reasons: the most important one is they have to stop before the end of the runway, another is they have to be going slow enough so the wings are not producing too much lift (causing them to go higher), another is they bounce back into the air from ground effect if they are going too fast - this can result in an accident because the plane bounces back up into the air (from the air pressure under the wings, not from the plane making contact with the ground) -- if the pilot doesn't react instantly and jam full throttle and abort his landing it usually results in overshooting the runway and a crash, in some cases it causes planes to bounce on this cushion of air and slide sideways off the runway. These are example of a plane TRYING to land but going too fast. The 757, on the other hand, was going so fast that the pilot would have had to literally fight to make it touch the ground - this is why it didnt come in sliding across the lawn. (Pretty sloppy layman's description, but it's fairly accurate. Feel free to read the links provided.) [edit on 15-9-2004 by CatHerder]

I say that because the tapes exist and have been withheld from th epublic domain with National Security cited as the reason, or so I've been led to believe from the material available on the internet. Would the Zapruder film ever be considered a non-issue? I want to believe this thread, but to my mind, the video tapes create a schrodinger aspect to an otherwise logical reason.
Originally posted by SkepticOverlord What makes you say that? There's plenty of other information that makes these tapes a non-issue.
With respect to the site, even this thread is available on the internet. It has become hard to discern what is the real explanation for any given event.
Originally posted by SkepticOverlord Ah-ha! There it is. The vast majority of the "material available on the internet" is conspiracy disinformationist tripe. Are we even certain these tapes do exist? After all, your only source is one that has already proven to have lied.
Maybe, and I state maybe the wing engine was hurled through... [edit on 15-9-2004 by LL1]
Originally posted by project_pisces Hate to tell you but a 757 fusealage, you know that tube where you sit that keeps ya safe at 38k feet? No way it could punch a perfect hole that deep into the Pentagon. I dont care if it was traveling at Mach3 Look at that cookie cutter perfect hole The 757 in all of its glory If you notice on the aircraft, even if the gear was retracted, the engines are so big and drop so low it would not allow the plane to attain that low of a fly in to strike where the hole ends at around the d-e ring(inner court)
You can cover it till your blue in the face, There is to much out there that could swing the evidence. I dont believe a human with little training, could pull this off. You have done alot of research, if you did it. Great job, I dont think I have ever claimed it wasnt a plane tha hit the pentagon. I am just giving my opioion, Thats all we all are doing. Yes you have a lot of time spent putting this together. Is this the first place you have posted it? You wated to get it all together, the get a membership here to post it? With the evedience you have passed, You would think you could go public.
