Cazalet33,
You say, after posting the findings of Mahon via the video's you commended
I haven't said that the crew were 100% blameless. I think they were complacent, just like everyone else in the causal chain.
And that is why this thread has been going for so long, Mahon took it upon himself to say the crew was blameless. As has been made evident, by many posters, many disagree with that opinion, and that is all it is, Mahon's opinion that is in dispute.
