Wow. Where do you guys get this shit? Is there a gulliblesuckers.com that posts this crap to be respewed on message boards?
Steel loses half it's structural strength at 600 degrees F. With it's load bearing ability severely compromised by the giant hole in the building collapse was definitely imminent. As more of the structure gave out, more stress was transferred to other parts.
Bullshit. Find me a source. Mild steel might, but properly rated structural steel maintains the majority of its strength at much higher temperatures. Even trying to swallow this little turd, how could parts of the structure that were never heated, such as the floors below those on fire, collapse at
free-fall speed? You're asserting that a structural steel superstructure core collapsed with nearly zero resistance under the weight of only a few of the floors above it impacting it after a drop of only 12 feet?
That's about as plausible as perpetual acceleration!
Doesn't it depend on what alloy is used? I'm sure there is some sort of steel that can withstand higher temperatures.
There is, it's called structural steel, and it was the material the superstructure core of the towers were built from.
I believe some of the fuels that where being pumped up there could have burned hotter then kerosene. second my grill has never collapsed on me. however I never had near 1/4 the weight it would take to collapse it under normal temperatures. It can hold my 150 pounds and when we are cooking there is never more then a few pounds of beef on it at a time.
Funny, on my detailed examination of the structure's schematics, I didn't see any gas lines. Nope, no gas on any floor above the 5th of either building.
Do you just make this crap up? Simple science provides all the answers necessary here.
No one has answered the other questions, though. What caused the other building to collapse? Did drywall (a fire-retardant) or paper (burns at 451 degrees F) or plastic or wood suddenly change physical properties and start burning at the 3000 degrees necessary to cause distortion in the structural steel? Where did the 'plane' go that 'crashed' in PA? The debris recovered by the NTSB only accounted for around 10% of the mass of the type of aircraft that supposedly crashed there. Did the rest of the aluminum, titanium, steel, and such simply vaporize? Where are the turbines from the engines? We've never had one disappear from a land crash before, but both were missing in PA.
Oh, and as to the messages... the most famous one could not be a more obvious lie. Listen to it again and think back: When was the last time you called your parents and identified yourself by your first and last name in the message?
Why can't commercial pilots consistently fly simulated aircraft into the buildings? Were these terrorists savant pilots? Top Gun grads?
Isn't it coincidental that less than a year before 9/11, Ashcroft and Cheney chimed in on a study whose conclusion was that America needed a 'polarizing event the likes of Pear Harbor' in order to lead the public to accept a bunch of civil liberty incursions, and then 9/11 happened, and nearly every incursion was instituted within 2 years?
Argue on, sheeple.
