To blame single pilot operation is idiocy in the wider context.
Why does it draw a greater conclusion upon the motivations of the manufacturer than the competence of a 10k hour pilot who can't achieve an appropriate and stable approach?
Then nevermind the penny wise approach saving a suggested $60k on additional pilots, what about the few hundred in landing fees at Farnborough v Blackbushe?
Very sadly people err this is startling but before panning single pilot ops are we suggesting that multi crews don't crash...? The lesson, as is so often the case, is there are few new ways to get killed in aviation and getting the fundamentals right keeps you at least safe.
