> The people authorized to open manhole covers could easily be trained to do it safely. Funny as it is, I would like to think that someone famous for his role in the investigation of the Challenger disaster would never flippantly say that a dangerous situation doesn't matter because "people … could easily be trained to do it safely." The fact that people can be trained to do something properly doesn't mean that trained people won't still sometimes do it improperly.
