I normally like to see some of the responsibility of the crash go to the PinC when discussing Erebus for all the oft discussed reasons, but to completely exclude the operating culture of the time is as bad as to try to completely exonerate the Captain of his responsibility. There will never be agreement on where the responsibility lies because people naturally like to lump it all in one place ( like you are doing PH6) when that is not how life works. There were serious decision making errors yes, but he wasn't operating in a vacuum, he was operating inan era and as a part of a particular culture when those errors were made. Peoples views will change with time as well. As a young turbo prop Captain I put the blame 90/10 on Collins. Now as a more experienced and older jet Captain I put it at about 70/30 on Collins......when I retire will it be 50/50? I doubt it but I wouldn't rule it out.
