The obvious additional level of excitement with helicopters is that the lifting surfaces are not only revolving at dizzying speeds, but are attached by hinges, dampers, bearing, nuts, bolts, locking wire and large dollops of engineering expertise. Compare this to a fixed wing where they cheat and use rivets, spars, bolts and welding. Having been an engineer before going flying, I often pondered how the the entire lift versus weight fight was being transacted thorough a single thrust bearing. Never bothered me (knowledge is power), but even today it's still some impressive engineering that fixed wing can only aspire to.
