P&P--agreed! You expressed it better than I did.
Hughes500--a helicopter jump is more of an amusement park ride to jumpers as opposed to the normal elevator service. Something to put in the jump logbook, a different flight adventure, and there is often the desire to experience a zero/low speed exit that is not possible with a regular, fixed wing jumpship. Zero/low speed exits are more challenging as the lack of relative wind makes body control more difficult. They are also the only exits that provide a momentary sensation of falling as the acceleration to terminal is not nearly as pronounced when the jump merely consists of changing one's vector from say 80KN forward to 100KN (approx. terminal) downwards.
