/" 757s dont go that fast. The airplane will just not do that, Russ Wittenberg, a retired pilot with United and Pan Am airlines, told AFP. "Its exceeding its air speed and mach speed limitations. The airplane just won't perform those maneuvers. The mach limit for a 757 is about 360 knots at 23,000 feet," Wittenberg said. / /Performance limitations on 767, 757. //http://www.757.org.uk/767/limits/index.html/ // /-----------------------/ // /"...considering that the air at low altitudes is much denser than that at normal cruising height, the pilots greatly exceeded Vne ("Velocity Never Exceed") and thereby risked disintegration of the aircraft by air friction." /"I spoke to a former Boeing 767-200 Captain about the aerodynamic limitations of the Boeing 767-200 aircraft and he stated that it would be unwise to exceed an indicated airspeed of 400 knots (460 mph at sea level) at _any_ altitude. "As mentioned before, the airspeed of 400 knots at sea level is well outside the maximum operating speed of the Boeing 767-200 and therefore the pilots would run the risk of either total structural failure or localised structural failures, namely wing fairings breaking off, engine cowlings breaking off, control surfaces breaking off or becoming inoperative and handling difficulties...." [Icke and Grossman-- version 3.2 , Dec. 2005, of "Ghost Gun UA175" ] http://dialspace.dial.pipex.com/prod/dialspace/town/pipexdsl/q/aqrf00/ggua175/ ---------------------------------------- *ANALYSIS OF SPEEDS* *of "UA 175"* Here is a list of UA175 speeds issued from official bodies that were presumably calculated using video footage of the WTC2 strike: Massachusetts Institute of Technology - 503 mph / 436 knots / M0.653 Royal Air Force - 575 mph / 500 knots / M0.750 Federal Aviation Administration - 586 mph / 510 knots / M0.765 National Institute of Standards and Technology - 546 mph / 475 knots / M0.714 Federal Emergency Management Agency - 590 mph / 514 knots / M0.771 "the hijacking story was complete BS, an absurdity which no-one who worked in the airlines believed......" Pilot of the big planes as told to G. Holmgren. Flt 77 at Pentagon: About the sharp descending turn made by the aircraft that hit the Pentagon at ground level, Wittenberg said: "The only air vehicle that could perform that would be a high-performance fighter jet, a remote controlled jet-powered drone, or a cruise missile." The fuselage of a 757 did not open that 16-foot hole, Wittenberg said. The aluminum of the fuselage would have crumbled like an egg shell on impact. Aluminum doesnt vaporize." There is no armor-piercing titanium on the tip of a 757, Wittenberg said. The white flash in the Pentagon video is the explosion of a high-energy explosive. The 12-foot hole is from the missile or the single jet engine aircraft that carried the missile. If a 757 had hit the Pentagon there would be two of these holes. "Boeing's not going to say," spokesperson Liz Verdier responded when asked about the 757's mach limit, "What does it matter?" she said, "How fast it was going is immaterial." Asked about Partin's theory that an aluminum-bodied aircraft both vaporized on impact and penetrated more than 9 feet of reinforced concrete, Marion Fulk, a retired chemical physicist and depleted uranium expert, told AFP: "I think what he's saying is nonsense The titanium engines would be more likely to penetrate than the fuselage." http://www.rumormillnews.com/cgi-bin/archive.cgi?read=70876 -------------------------------- * * About Partin's theory that parts of the aluminum aircraft vaporized on impact while the thin-skinned fuselage bored through nine feet of reinforced concrete, Paul F. Mlakar, technical director of the Pentagon Building Performance Report sponsored by the American Society of Civil Engineers (ASCE), told AFP, "I'm a little skeptical." Mlakar, with the U.S. Army Corps of Engineers, thinks the 12-foot hole in the "C" ring was caused by an "avalanche of debris." That's where the black box was found, Mlakar said. The National Transportation Safety Board (NTSB), who received the black box, told Mlakar _the plane was traveling 460 knots, or 530 mph. The NTSB refuses to say anything about the black boxes saying it has turned over all data to the FBI._ ----------------- malaprop aka izzy Search the archives for political-research at http://www.terazen.com/ Subscribe to the RSS feed for political-research at http://rss.groups.yahoo.com/group/political-research/rss Yahoo!
