I'd like to take this opportunity to recommend the HBO series 'From the earth to the moon', (one episode of which, incidentally, cover the Apollo 1 accident.)
I found this to be a very interesting, well made and also deeply moving series and an absolute must for anyone interested in space flight. Each episode considers different aspects of the Gemini and Apollo programmes.
BTW I don't get a cut from HBOs DVD sales, though perhaps I ought to!
