a factor to consider is that the more engines you have the more likely you are to experience an IFSD.
Is this not just a red herring? You will no doubt claim it misleading to suggest that this means the safest aircraft will necessarily have one engine. However, when you work out why such a deduction is wrong will that not also suggest why your claim, as quoted above, is completely misleading and a distraction from the issues at hand?
