This Thursday, the Chico News and Review will be doing a story covering the pro and cons of the people that have been lobbying editor Evan Tuchinsky for more coverage of the alternate 9/11 theories that are being pushed around the country by conspiracy thinkers.
One of the central themes of the group 911Truth.org is that the World Trade Center was brought down with explosives, rather than the engineering failure reports which point to the fire caused by the jet fuel, shocked off fireproofing, and steel trusses that weakened and allowed for a domino effect implosion and collapse.
Of course some people think 911Truth.org is just part of the tinfoil hat crowd. But this past weekend the very same set of conditions that pitted fire against concrete and steel occurred at the gasoline tanker truck accident at the I880/580 interchange in Oakland creating an accidental laboratory to illustrate the proof that fire can indeed make steel and concrete structures fail.
For all those whom cling to the alternate fantasy belief that the World Trade Center towers could not have been brought down by burning jet fuel creating an inferno that melted steel, but rather, it was explosives planted by some conspiracy, the collapse of the I-880/580 Interchange in Oakland Sunday from a burning tanker truck should provide clear empirical proof that fire can easily take down steel and concrete structures.
Engineers estimated that the flames at the bridge reached close to 3,000 degrees Fahrenheit. Steel is known to lose half of its rigidity at 1,000 degrees F and begins to melt at 2,750 degrees F.
People may conjecture myriads of alternate theories, but the laws of physics are absolute, unless of course you wear a tinfoil hat, then anything is possible.
Melting Points for Comparison
Engineers estimate Sunday’s I-880/580 flames reached close to 3,000 degrees. Here’s a breakdown of melting temperatures (In Fahrenheit) for some materials.
Molten lava: 3,140°
Iron melts: 2,797°
Steel melts: 2,750°
Gold melts: 1,947°
Silver melts: 1,763°
Steel loses half its rigidity: 1,000°
Lead melts: 622°
Water boils: 212°
