do you think it right to exonerate the crew of this aircraft for causing this accident?
I don't, no. But I think what you're asking is "is there anything to be gained by aportioning blame?"
Mahon said the crew made no error that contributed to this accident. That, to me, is patently false, and worth arguing against even nearly 40 years later. Over and above that I have no interest in debating whether the crew were 90% responsible or 20% responsible. But to absolve them from blame is to condone the poor airmanship they displayed and as a pilot I just can't let that lie.
