Shuttle Problem?

A couple of short strips of filler material dangling from Discovery's belly had NASA scrambling Sunday to determine whether the protrusions might endanger the space shuttle during re-entry and whether the astronauts should attempt a repair. The potential trouble has nothing to do with launch debris, but rather material used to fill the spaces between thermal tiles, a common problem in the past although not necessarily to this extent. Flight director Paul Hill said engineers will spend the next day analyzing the situation and decide Monday whether to have the crew's two spacewalkers cut, pull out or shove back in the hanging material.
