It seems that now Dittmore has all but dismissed tile damge on takeoff as the cause of the breakup. He said at the briefing yesterday that the foam just isn't hard enough to produce the type of damage that would cause the tiles to fail. So, according to him, they're back to the drawing board.

On another note, here's one for the Darwin Awards...it's announced that taking and possessing pieces of the shuttle wreckage is a federal offense. So no less than 17 people took wreckage and posted it for sale on eBay with all their required contact information. They are all presently being visited by federal agents.
