How about explaining what you just said a little more. Just saying that something is foolish doesn't make it so. How do aluminum planes slice into steel and concrete without even slowing down? The tail sections didn't even snap off! LOL See below for what I mean. You are thinking of the relative hardness (scratch resistance) of steel and aluminum, which would be an issue if the plane were used as a cutting tool. You should be thinking of tensile strength of steel pipes, because the plane was used as a hammer or projectile. Here is an example, which is pretty close to what happened. Suppose you build a table whose legs are four wooden dowels half an inch in diameter. You put a thousand pounds of stuff on the table top and the legs hold. That's because wood has high compression strength, or what engineers call bulk modulus. Now hit one of the table legs in the middle with a hammer. It breaks and the table tips over. Note that it breaks as easily with a hardened steel hammer as with a rubber hammer. In both cases, the breaking is a function of the hammer's mass times velocity squared, not its hardness. You're not cutting the dowel, you're stretching it until it breaks. Wood has low tensile strength, which engineers call Young's modulus. If you wanted to make table legs resistant to a blow from the side, you would have used thin steel I-beams. You didn't because the engineering spec talked about supporting weight, not resisting blows from the side. Notice the hammer's velocity is squared. If you could increase the hammer's speed from 20 mph to 600 mph, it wouldn't be 30 times stronger, it would be 900 times stronger. If you could move a two pound hammer at 1,000 feet per second, it would be equivalent to swinging a one ton hammer. Do you imagine a one ton hammer could break a 30 foot steel pipe? Consider that a Boeing 767 is a 400,000 pound hammer. Weren't the WTC buildings built to withstand an airplane crash? Yes, but that tensile strength is in the central core, not the peripheral frame. The spec didn't say the plane would bounce off, it said the building wouldn't topple nor collapse on itself. It didn't .. not from the plane crash.

Whether they were all getting their information from one source or not is something I can't answer. What I do know is that what they showed was fake. I don't know if you're aware of this or not, but I also posted links right from those major media sources just in case someone like you might question whether the documentaries are showing the actual news footage. There is a foolproof way to coordinate media -- make it happen in reality. It has the additional benefit of agreement between media reports and eyewitnesses, plus they don't have to kill snitches.

So, you agree the buildings were collapsed with demolitions and yet it seems impossible to you that they could have done that much work secretly without the building manager finding out? That's what I've been SAYING! LOL The building "management" (whoever that is) was IN on it. Um...Silverstein? Here is evidence: scientists find active nano-thermite in WTC dust gathered from multiple sites.
http://www.bentham.org/open/tocpj/artic ... .pdfTurner Construction had offices in the basement of WTC 1, did extensive refurbishing on structural beams in elevator shafts and also fireproofing sprayed on beams. It was one of the contractors who hauled away wreckage. It has extensive experience with demolition, often works with Controlled Demolitions Inc (CDI), does classified work for DoD, and is the only source for nano-thermite in NYC. Its CEO in 2001 was Tom Lepper, who went on to become mayor of Dallas and was named to President's Commission on White House Fellows by George Bush.Pasquale DiFabrizio wrote:Robert Wagner wrote:767 speed: The plane was descending 10,000 feet per minute -- a power dive. There is no evidence of 767 max speed. The best Pilots for 911 Truth came up with is RA990 power dive at 22,000 feet, for which they never give speed, only "equivalent dynamic effects." This is hand waving. The speed of sound at sea level is 661 knots (@15C). Two sources give the plane's speed at 510 and 542. That's only .77 to .82 Mach, which is below the conservative Boeing spec of .86 Mach. Actual limit is between .86 and .99 Mach.
http://pilotsfor911truth.org/p4t/Radar_ ... 75.pdfWhat power dive? Why do some of the supposed authentic videos show the plane coming straight in horizontally or at a slight angle? (See the short video below.). There was no power dive, at least no power dive involving commercial jets. The plane that hit the south tower, for example, comes in basically horizontally.THIS is a power dive?
http://www.youtube.com/watch?v=zLKYr5hA6s8Also, I'm sorry, but those Boeing 767 cannot fly horizontally at basically sea level at 500+ mph. They just can't. I don't care what the speed of sound is at sea level.You are seeing the tail end of a power dive, after it leveled off. A bicycle can't go faster than 30 mph on level ground (without drafting), but it can easily hit 60 mph coasting down a steep hill. After it hits level ground at the bottom of the hill, it will continue going 60 mph for awhile. Descending 10,000 feet per minute is a 20% grade. One of the steepest LONG roads in the US descends 5,000 feet in 10 miles, from Cloudcroft to Alamogordo NM. That's only 10%. (I've done it several times.) The steepest roads in San Francisco are less than 20%. Pittsburgh and Los Angeles have a few short roads over 20%. They have stairways instead of sidewalks.The plane was in a steep dive expressly to build up speed greater than it could achieve in level flight. Remember, the speed of the hammer is squared.

Two sources give the plane's speed at 510 and 542.I don't care what the speed of sound is at sea level. Boeing 767s cannot fly at sea level at the speed of sound. They'd fall apart. The air is too thick. Also, whatever "sources" your talking about are lying to you. The air is too thick, and the engines would need something like six times the thrust. There was no power dive as evidenced by the news coverage.Thrust came from gravity. They were only going .8 Mach. In the real world, they didn't fall apart. My lying reference was NTSB, who got it from radar data.

It proves they were inept, not complicit. You can believe what you want if it makes you feel better. I don't buy it, FAA knew AA11 was hijacked at 8:20, because a flight attendant told them. They notified NORAD at 8:38, 18 minutes later. Fighters were scrambled from Otis at 8:46, same time WTC 1 was hit, airborne at 8:53.FAA suspected UAL175 was hijacked at 8:47, because it changed transponder code and flight path. They notified NORAD at 9:03, 16 minutes later, same time the plane hit WTC 2. FAA knew AA77 was hijacked at 8:47. They notified NORAD/NEADS at 9:34, 38 minutes later, when NEADS called THEM to ask whether they had missing planes. The plane hit the Pentagon at 9:37 or 9:32, depending on whom you believe. FAA suspected UAL93 was hijacked at 9:28. They called NORAD at 10:07, 39 minutes later, 4 minutes after the plane had already crashed in Shanksville. Fighters were launched from Langley at 9:30, but no one told them where to go nor what to look for. So they flew their training route over the Atlantic Ocean until someone told them what to do at 10:00. With government like this, diversionary exercises and stand-downs proved to be superfluous.
