About levees and explosions

One alarming rumor that was repeated by many survivors in New Orleans was the allegation that the levees were blown up. People reported hearing explosions at the time of the levee failures.

Calm down folks. Boing Boing provides some links to an analysis by a "geographer" explaining how a levee failure could go BOOM. I've also read that there was a barge that broke loose and either accompanied the storm surge -- or maybe was sucked into the breach? -- which might have slammed into something with a BOOM.

Another wild rumor bites the dust.
