And Thus Is Another Conspiracy Theory Vaporized in the Laboratory of Life

"9/11 was an inside job" whacknuts claim shit like:

Rosie O'Donnell is correct. Jet fuel fires do NOT melt steel; even really big jet fuel fires can't melt steel. Jet fuel burns at only about 1500 Degrees Fahrenheit in the open air and structural steel does not melt or even get significantly weakened until more than a thousand degrees hotter with a melting point of near 3300 degrees F. That is why diesel engines and jet turbines can sustain internal combustion without melting and why steel workers use acetylene torches, not jet fuel fires, to cut steel.

But an unfortunate incident (but thankfully, not a tragic one unless you are a Bay Area commuter), pretty much lights up this particular crock:

San Francisco Bay area residents faced nightmarish commutes Monday after one of the region's most traveled sections of freeway melted and collapsed following a fiery crash.

An elevated section of highway that carries motorists from the San Francisco-Oakland Bay Bridge to a number of freeways was destroyed early Sunday after heat from an overturned gasoline truck caused part of one overpass to crumple onto another.

***

The crash occurred around 3:45 a.m. on the MacArthur Maze, a network of ramps and interchanges at the edge of downtown Oakland and about a half-mile from the Bay Bridge toll plaza. Witnesses reported flames rising up to 200 feet into the air.

Heat exceeded 2,750 degrees and caused the steel beams holding up the interchange from eastbound I-80 to eastbound Interstate 580 above to buckle and bolts holding the structure together to melt, leading to the collapse, California Department of Transportation director Will Kempton said.

OK, so jet fuel burning in an enclosed space with all kinds of fuel - desks, drywall, paper etc. - to stoke it can't reach a temperature high enough to compromise steel...

...but a gasoline tanker truck burning in open space atop a concrete and steel bridge deck has sufficient heat (it should be noted that the driver was only slightly injured) to cause that to collapse.

Say, that driver did walk away from the conflagration with only a mere scratch. Funny. It's like he knew it was going to happen...

We're through the looking glass here people.
