I often think pilots, and regulators for that matter, miss the point when considering single engined helicopters versus twins as being inherantly less safe. After all, however many engines you've got, you've still only got one main gearbox, one T/R, one pitch change link to each rotor blade etc. There are a long list of components you only have one of that if they fail, you're going to die, quickly! Why get so worked up about the need for more engines. J
