Lessons of the San Fran Bridge Collapse
Reprinted below is one for the conspiricy loons.In one line of inquiry that could improve future responses, some scientists were studying linkages between the freeway collapse and how the World Trade Center came down on Sept. 11, 2001. The structural failures appear similar, said David McCallen, division leader in nonproliferation, homeland and international security at the Lawrence Livermore National Laboratory. So he's in on the conspiracy, too! The steel supporting the overpass turned pliable after the gasoline-fed fire below reached temperatures up to 2,000 degrees - more than four times as hot as the hottest conventional home oven. Pliable. The engineering term is plastic. Not melted. Whaddaya say, Rosie?
