This Is An Accident Waiting To Happen
So apparently the astronauts that are on the space shuttle Discovery are going to have to repair their own ship. They're going to have to do something no other space crew has done: send a astronaut beneath the shuttle to repair filler sticking out between the tiles on the ship's belly.
I'm no expert at all this stuff, but while they are in (roughly) zero gravity in outer space, they're going to be orbiting Earth, right? That means they're be traveling through space really stickin' fast while they're doing this repair. There is obviously little room for error. It just makes me think of something I heard on the radio this morning: It'd be like if you were flying down the highway at 100 mph and realized your tailpipe was a bit loose, and wanted one of your passengers to crawl under the car (as you continued to haul tail down the highway) and fix it.
I just hope they all make it home safe.
