I do agree. Absolutely.
I had't done much reading on this accident, the 40th anniversary got my interest. The more I read the more I questioned the 'whole' story. It appears there are two camps, those hell bent on blaming Collins, those hell bent on blaming Air New Zealand. Personally I think the causal factors of this accident are incredibly complex, perhaps if politicians, in particular one had kept their nose out of things the accident report may have had a chance.
