If you're not familiar with the event and the people and systems around it, the Wikipedia article reads as thorough and remarkably unbiased, to me.
I will remember as long as I can what I was doing that day and how I saw the news. I will also remember Feynman's publicity stunt at the commission hearings, which I had been watching. I regard the astronauts as heroes and the NASA/Thiokol managers of that time as villains, mealy-mouthed excuse-makers who should at the very least have resigned in shame. That it was Feynman's impassioned grandstanding to call adequate public attention to their failures is what endeared him to me.
