NASA is an organization, like FR is. I agree that some people in NASA must have had their heads in the sand on QA safety requirements.
So do too many freepers. They lap up the few crumbs that NASA tosses their way and seem to be satisfied, yet indignant if anyone expresses skepticism. Well, like you, I am very skeptical. Seven fine people are dead and I don't buy that it was an accident.
I'm not saying that it was a sinister plot, but I'd like to get at the root of the problem.
