Flight 93 - What really happened?

"Melted" Steel
CLAIM: "We have been lied to," announces the Web site AttackOnAmerica.net. "The first lie was that the load of fuel from the aircraft was the cause of structural failure. No kerosene fire can burn hot enough to melt steel." The posting is entitled "Proof Of Controlled Demolition At The WTC."

FACT: Jet fuel burns at 800° to 1500°F, not hot enough to melt steel (2750°F). However, experts agree that for the towers to collapse, their steel frames didn't need to melt, they just had to lose some of their structural strength--and that required exposure to much less heat. "I have never seen melted steel in a building fire," says retired New York deputy fire chief Vincent Dunn, author of The Collapse Of Burning Buildings: A Guide To Fireground Safety. "But I've seen a lot of twisted, warped, bent and sagging steel. What happens is that the steel tries to expand at both ends, but when it can no longer expand, it sags and the surrounding concrete cracks."

"Steel loses about 50 percent of its strength at 1100°F," notes senior engineer Farid Alfawak-hiri of the American Institute of Steel Construction. "And at 1800° it is probably at less than 10 percent." NIST also believes that a great deal of the spray-on fireproofing insulation was likely knocked off the steel beams that were in the path of the crashing jets, leaving the metal more vulnerable to the heat.

But jet fuel wasn't the only thing burning, notes Forman Williams, a professor of engineering at the University of California, San Diego, and one of seven structural engineers and fire experts that PM consulted. He says that while the jet fuel was the catalyst for the WTC fires, the resulting inferno was intensified by the combustible material inside the buildings, including rugs, curtains, furniture and paper. NIST reports that pockets of fire hit 1832°F.

"The jet fuel was the ignition source," Williams tells PM. "It burned for maybe 10 minutes, and [the towers] were still standing in 10 minutes. It was the rest of the stuff burning afterward that was responsible for the heat transfer that eventually brought them down."
 
Widespread Damage
CLAIM: The first hijacked plane crashed through the 94th to the 98th floors of the World Trade Center's 110-story North Tower; the second jet slammed into the 78th to the 84th floors of the 110-story South Tower. The impact and ensuing fires disrupted elevator service in both buildings. Plus, the lobbies of both buildings were visibly damaged before the towers collapsed. "There is NO WAY the impact of the jet caused such widespread damage 80 stories below," claims a posting on the San Diego Independent Media Center Web site (sandiego.indymedia.org). "It is OBVIOUS and irrefutable that OTHER EXPLOSIVES (... such as concussion bombs) HAD ALREADY BEEN DETONATED in the lower levels of tower one at the same time as the plane crash."

FACT: Following up on a May 2002 preliminary report by the Federal Emergency Management Agency (FEMA), a major study will be released in spring 2005 by the National Institute of Standards and Technology (NIST), a branch of the U.S. Department of Commerce. NIST shared its initial findings with PM and made its lead researcher available to our team of reporters.

The NIST investigation revealed that plane debris sliced through the utility shafts at the North Tower's core, creating a conduit for burning jet fuel--and fiery destruction throughout the building. "It's very hard to document where the fuel went," says Forman Williams, a NIST adviser and a combustion expert, "but if it's atomized and combustible and gets to an ignition source, it'll go off."

Burning fuel traveling down the elevator shafts would have disrupted the elevator systems and caused extensive damage to the lobbies. NIST heard first-person testimony that "some elevators slammed right down" to the ground floor. "The doors cracked open on the lobby floor and flames came out and people died," says James Quintiere, an engineering professor at the University of Maryland and a NIST adviser. A similar observation was made in the French documentary "9/11," by Jules and Gedeon Naudet. As Jules Naudet entered the North Tower lobby, minutes after the first aircraft struck, he saw victims on fire, a scene he found too horrific to film.
 
g Plane, Small Holes
CLAIM: Two holes were visible in the Pentagon immediately after the attack: a 75-ft.-wide entry hole in the building's exterior wall, and a 16-ft.-wide hole in Ring C, the Pentagon's middle ring. Conspiracy theorists claim both holes are far too small to have been made by a Boeing 757. "How does a plane 125 ft. wide and 155 ft. long fit into a hole which is only 16 ft. across?" asks reopen911.org, a Web site "dedicated to discovering the bottom line truth to what really occurred on September 11, 2001."

The truth is of even less importance to French author Thierry Meyssan, whose baseless assertions are fodder for even mainstream European and Middle Eastern media. In his book The Big Lie, Meyssan concludes that the Pentagon was struck by a satellite-guided missile--part of an elaborate U.S. military coup. "This attack," he writes, "could only be committed by United States military personnel against other U.S. military personnel."

FACT: When American Airlines Flight 77 hit the Pentagon's exterior wall, Ring E, it created a hole approximately 75 ft. wide, according to the ASCE Pentagon Building Performance Report. The exterior facade collapsed about 20 minutes after impact, but ASCE based its measurements of the original hole on the number of first-floor support columns that were destroyed or damaged. Computer simulations confirmed the findings.

Why wasn't the hole as wide as a 757's 124-ft.-10-in. wingspan? A crashing jet doesn't punch a cartoon-like outline of itself into a reinforced concrete building, says ASCE team member Mete Sozen, a professor of structural engineering at Purdue University. In this case, one wing hit the ground; the other was sheared off by the force of the impact with the Pentagon's load-bearing columns, explains Sozen, who specializes in the behavior of concrete buildings. What was left of the plane flowed into the structure in a state closer to a liquid than a solid mass. "If you expected the entire wing to cut into the building," Sozen tells PM, "it didn't happen."

The tidy hole in Ring C was 12 ft. wide--not 16 ft. ASCE concludes it was made by the jet's landing gear, not by the fuselage.
 
light 77 Debris
CLAIM: Conspiracy theorists insist there was no plane wreckage at the Pentagon. "In reality, a Boeing 757 was never found," claims pentagonstrike.co.uk, which asks the question, "What hit the Pentagon on 9/11?"

FACT: Blast expert Allyn E. Kilsheimer was the first structural engineer to arrive at the Pentagon after the crash and helped coordinate the emergency response. "It was absolutely a plane, and I'll tell you why," says Kilsheimer, CEO of KCE Structural Engineers PC, Washington, D.C. "I saw the marks of the plane wing on the face of the building. I picked up parts of the plane with the airline markings on them. I held in my hand the tail section of the plane, and I found the black box." Kilsheimer's eyewitness account is backed up by photos of plane wreckage inside and outside the building. Kilsheimer adds: "I held parts of uniforms from crew members in my hands, including body parts. Okay?"
 
Jks, Im really glad you found that site
 
Oh yes, the famous popular mechanics article.

Funny nobody else published this sort of nonesense.

It's time to wake up folks and start doing something about the way our world is headed. The only way to find peace on earth is to fully expose the Global Elite, the New World Order so that they can crumble. No secret organization can handle being uncovered and that process is happening now.

I just hope there is still time but, I fear the plans have been in motion for far too long and are reaching it's climax. Those of you who are living in America, I'd be very afraid right now. You are one 'terrorist' attack away from becoming a full Police State and that's a very scary thought. Remember Nazi Germany? Yeah, well, welcome to the beginnings of Nazi America (better yet, Nazi World)... without the Nazi's.
 
Another wacko.
Prove it wrong.

Stop living in a fantasy world
 
The fact of the matter is that the popular mechanics article sites more sources than all of these conspiracy sites combined.
And they're credible sources at that.

I'm doing my part to debunk this stupid crap some of you keep posting.
 
Awesome, instead of attempting to rebutt anything stated, you just go on another delusional conspiracy fanboi rant.

I laugh at you and your conspiracy nut bretheren

Funny how facts backed by credible sources shut you the hell up.
Just goes to show.
 
Um, you realize that I don't have a computer with me at all points of the day right?

Either way, I hope you all remember the conversations some of us are having now because, when everything goes to **** (and it will) you'll have nobody to blame but yourselves for not being prepared.

Go on napping my friends. I'm sure WWIII will wake you up... maybe.

Sounds like he mis-spoke. He was referring to the terrorists shooting down the plane. It sounds like he meant to say they brought the plane down, not shot it down.

Plus there's plenty of 911 evidence (meaing the number 911, which was dialed by a few on the plane), and evidence from other recordings, which indicates that the plane wasn't shot down, but was crashed by the terrorists.

Rumsfeld's quote is this:

"I think all of us have a sense if we imagine the kind of world we would face if the people who bombed the mess hall in Mosul, or the people who did the bombing in Spain, or the people who attacked the United States in New York, shot down the plane over Pennsylvania and attacked the Pentagon, the people who cut off peoples' heads on television to intimidate, to frighten – indeed the word 'terrorized' is just that. Its purpose is to terrorize, to alter behavior, to make people be something other than that which they want to be."

He said the "people who attacked the United States in New York, shot down the plane over Pennsylvania". That isn't referring to the plane being shot down by the U.S. military. He mis-spoke, saying that the terrorists shot down the plane, which also is not correct, nor a part of any conspiracy theory I've yet to hear.

Exactly.
