If there are any other Shuttle fans out there, Roger Boisjoly has passed on. For those who don't know the name, he was an engineer for Morton-Thiokol, who were the contractors for the Solid Rocket Boosters. He noticed on post-flight analysises of several missions prior to Challenger that the SRB O-rings were coming dangerously close to failing. With dire consequences, Thiokol basically ignored him. They did set up a task force, but without any authority or support from leadership. He also voiced concern about the low temps the night before 51-L. A moment of silence for a man who put safety first, when almost no one else did that day.

Well said, Dana.
