I have no problem using common sense and delaying launches for weather problems, what I am against is delaying launches in an effort to make the shuttle perfectly "safe" for operation. I doubt space travel will ever be an everday mode of travel. People needs to realize that space travel is similar to a war in that losses are going to happen.
I totally agree.
I think the big problem is though, you won't get funding taken away if you have a submarine disaster but after Challenger and the more recent reentry disaster, they could very well pull the rug out from under NASA or at least the shuttles, if another major disaster were to happen.
The general public doesn't get it, and would see it as an unnecessary expense of life because of NASA's negligence. They do believe that the shuttle should be failsafe.
