I dont think it would really be possible to make fair comparisons, by there very nature some types of heli operations are obviously going to be more dangerous then fixed wing flying,
Statisticians won't take into account things like firefighting, flying over hostile terrain, logging, long lining and dangerous SAR missions etc etc..
Minor incidents in cars and little dents and rearending will normally go unreported, but every little thing has to be reported in a helicopter!
Flying in a space shuttle would not be the safest form of transport but wouldn't you like to give that a shot!!
