CHEAP TILE

I admired John Glenn's courage when he let them shoot him up into space in that little old tin can. Scared me just to think about it, but the vehicle seems to have had some substance to it, if diminutive in size. Now this crowd up there in the shuttle are apparently oribiting around in a really flimsy piece of junk. They needed to repair it but were afraid to touch the tiles for fear that they'd fall off or otherwise be damaged. What kind of tiles are that fragile or so insecurely fastened on? Why would NASA send a crew up in something so dangerous? I advise this crew to get down as soon as possible. If that contraption they're riding around in is so fragile that it's likely to be damaged by simply touching, let alone by an astronaut bumping it, I say get out.
