Rosie O'Donnell, structural engineer: "(The collapse of World Trade Center 7 on 9/11) is the first time in the history of the world that fire has ever melted steel."

Earlier today, in the Bay Area:

The tanker carrying 8,600 gallons of gasoline ignited around 3:45 a.m. after crashing into a guardrail on the interchange connecting westbound lanes of Interstate 80 to southbound Interstate 880. A preliminary investigation indicates he may have been speeding as he navigated the curving road, Cross said.

Heat from the flames melted a second interchange from eastbound I-80 to eastbound Interstate 580 located above the first interchange, causing a 250-yard section of the roadway to collapse onto the crash scene below, according to the CHP. Witnesses reported flames from the blaze rose up to 200 feet into the air.

Late Sunday morning, the charred section of collapsed freeway was draped at a sharp angle onto the highway beneath, exposing a web of twisted metal beneath the concrete.

Has anyone even tested for explosive residue? Were there any Halliburton employees in the area at the time? Where was Dick Cheney at 3:45 a.m. this morning?
