All over Florida! (bad Challenger joke).
But seriously, Steven Robinson, the astronaut attached to the giant robot arm, was able to extract the two pieces of toilet paper stuck to the bottom of Discovery's shoe. Luckily, he didn't have to use scissors or build a hacksaw in space. I think the bigger, neglected question is, how can that be good, this "filler material" just coming out from between tiles like that. If I were up in space, I'd be having a panic attack.
Now there are new developments, of course. A heat blanket or something that is outside of a crewman's window is puffed up. NASA and other powers that be are deciding if this is going to warrant yet another spacewalk to repair, cut or rip off the offending blanket.
I'll keep you posted.
