...<SNIP>... Don't want to get political here but dam you Ray Gun & Bush....
I would also highly recommend the book "Truth, Lies, and O-Rings" by Allan J. McDonald.
This is a real eye-opener about the mismanagement and bad decisions that led to the accident, as well as the cover-ups and attempts to hide the truth after the accident.
(McDonald was one of the leading engineers at Morton Thiokol, which was the company that built the SRBs. He was one of the very few people who always stood by the truth and had the guts to stand up against the cover-up attempts of the managers of the company he worked for.)
