Certified: Why did the steel fail before 2 hours if it was certified?

Because it wasnt certified to withstand the stresses imposed on it after the impact AND fire.

And before you break out the calculations, no one will EVER know just exactly how much damage occured within the towers.
which defies nature and UL's own certification of steel, and Kevin Ryan, the ethical whistleblower, became a target of vicious malice of forethought by the Bush administration.
One problem with carbon based fuels and secondary carbon based sources is, they cannot produce enough thermal energy to begin to compromise steel, much less heat it enough all the way to the center, from all sides, to begin to bend steel

And Kevin Ryan the WATER TESTER, with absolutely no connection to the construction materials division, took it upon himself to say that something was wrong because his company certified the steel........

ROTFLMAO....the engine shop guys in my squadron would LOVE to talk to you about that one. It took them five minutes to quit laughing. JP-8 burns hot enough to MELT steel, it is only the design of jet engines which uses bypass intake air to insulate the steel of the combustion chamber from the burning fuel.

We have 163 F-15s currently grounded, because of cracks, that should NOT have happened due to the engineering and testing put into the structural members of the F-15s.
The hull plates of the Titanic were tested, and engineered...and failed in spectactular fashion.
The steel used to build the Titanic was not as "impact-resistant" as modern steel, according to Dr. H.P. Leighly, a professor emeritus of metallurgical engineering at UMR. But it was the best steel available at the time, says Leighly, who studied some 200 pounds of steel from the wreckage.
Inferior steel wasn't the only reason the luxury ocean liner Titanic sank in the early morning hours of April 15, 1912. Other factors -- such as flaws in the ship's design, the crew's negligence and the lack of lifeboats -- also contributed to the disaster, Leighly says.
...the elevated walkways of the Hyatt in Kansas City were engineered..and failed...the Tacoma Narrows bridge, designed, engineered, tested...and failed...
Quite frankly, we STILL do not know everything about chemistry or physics and it is the ultimate in human arrogance to assume we do.
The facts are.....The towers failed and collapsed due to the damage sustained and the fires.

Outside of powering aircraft, JP-8 is used as a fuel for heaters, stoves, tanks, internal combustion engine powered electrical generators (as a replacement for diesel fuel), and other military vehicles, and serves as a coolant in engines and some other aircraft components.
it is only the design of jet engines which uses bypass intake air to insulate the steel of the combustion chamber from the burning fuel.

I fail to believe everyone in the military is as much of a science neophyte as you project yourself to be in these discussions, including ""......the engine shop guys in my squadron..."
Jet A-1 is similar to JP-8
JET A-1
Flash point: 38 °C
Autoignition temperature: 210 °C
Freezing point: −47 °C (−40 °C for JET A)
Open air burning temperatures: 260–315 °C (500–599 °F)
Maximum burning temperature: 980 °C (1796 °F)
Density at 15 °C (60 °F): 0.775–0.840 kg/L
Most steel has other metals added to tune its properties, like strength, corrosion resistance, or ease of fabrication. Steel is just the element iron that has been processed to control the amount of carbon. Iron, out of the ground, melts at around 1510 degrees C (2750°F). Steel often melts at around 1370 degrees C (2500°F).

What makes him a lunatic? Lets see, he works in a water testing lab and sees fit to speak out in his "official" capacity that something is wrong because his company certified the steel. Neverminding the fact that the steel used to construct the WTC was used long before he was even a water tester at UL. Sorry, but thats nuts to me.
