Well, the final report on the Columbia accident is in, and it is a rather damning review of the culture of NASA. However, it does not really get to the crux of the problem: that is, that the space program is being run by the government. All of the problems that led up to the disaster of February 1,2003 stem from that.... ie it is a SPACEcraft with WINGS fercryingoutloud. why? because the politicians in charge think that flying a spacecraft with wings is sexy. I could go on, but I won't just now, as every time I get on this topic I only succeed in pissing myself off.
