![]() most of the hijackers had relatively common arabic names, so it is no surprise that people with identical names were found alive later. I found this paper really interesting: Although they don’t explain what “other paint” they compared it to-the color & texture looks like normal Red Oxide Paint to I’m going to step away too, after this 1: Larger pieces were found, e.g. There are a few, however, that present really interesting data, with solid conclusions. ![]() Many of them that specifically refute the NIST and Balant papers don’t follow strong lines of reasoning, or offer calculations to support their positions. I’ve been reading about the papers linked to-a lot of them have very very interesting content, and I suggest you read them. (Which lends itself to an approach similar to the whole Pearl-Harbor-was-let-happen thing, along with some explosives to make sure the theatrics brought down the building). Heck, if that video is to believed, Bin Laden didn’t even think he’d collapse the whole tower. I doubt the towers would have been rigged with explosives-that just wasn’t considered a possibility, and the structural fire in 1975 would have set it off. (This could have happened explosives or no explosives) (ref article The leaning-over part has been long since discussed-the structure below couldn’t continue to hold it up, and essentially “kicked out” from under it, because of the mass & speed involved, the top section landed within the footprint. Apparently annealing studies done on steel found in the wreckage found it had been heated to 600C by the fires. Oh, and the molten metal: Melting point of aluminum is 660C, however can be lower for aircraft alloys, e.g. (This is a good white paper on the subject: ) It accelerated down through the rest of the floors at near free-fall speed-were it being significantly slowed down by them, it would have tumbled off, but since the floors below were being loaded (by the falling structure) at much higher than they could withstand, they simply failed. If you think of it as the top of the building “snapped off”. In short, the structure of the building above the impact (core and all) fell through the remaining floors. The upper part of the building was being held up by the hat trusses holding it back to the core, once the fire weakened enough of the structure, the core began to collapse. The steel didn’t need to heat up enough to fail, just enough to become not-strong-enough. Question 5: How can there be pools of molten metal on all three towers after their collapse since the metal to melt needs 500 degrees Fahreneit more than the jet fuel even burns? Can this be done according to the pancake theory? ![]() Question 4: How can 110 flours and the core columns fail alltogether and fall apart in just 10.30 secs? This is the speed of a free fall from that height. How can there be structural failure on all three towers? Question 3: Les Robertson (WTC structural engineer) states that they designed a building able to sustain a hit from a Boeing 707 from any side.Frank Demartini (WTC construction manager) adds that WTC was able to sustain multiple aircraft impacts.Aaron Swirsky (WTC architect) also adds that the building was designed to cope with a very bigger hole than the one inflicted to the building. As an engineer i would expect that according to this theory the core column (consisting of 47 reenforced massive steel colons) should be standing.How could a plane cut all these core colons? Question 2: The pancake theory suggests that the fire heats up the steal suficiently for the floors to brake loose from the steel main columns and start a chain reaction. Question 1: How can the passport of the highjacker (which proved later was alive and well) pass through the fire and pulverised concrete one piece since the biggest piece the firefighters found is half a phone panel. ![]() Trade Towers 1, 2 and 7 collaped due to structural failure through fire in a “pancake” fashion. The official statement of the US government is that W. I don’t know anything about 9/11 and the WTC collapse besides what was published through the internet,radios and tv so i imagine you americans can enlighten me on this matter. I live in Greece and i am a young engineer.
