Years ago I did a statistical comparison between helicopters and other modes of transportation, the fatality rate is less than motorcycles operated on public roads.
Which brings up an interesting point about comparison of auto and aircraft accident rates. It might make more sense to base comparison numbers on accidents/trip rather than per mile, as the median aircraft trip might be 500 miles and the median car trip might be 5 miles; the average driver might make 500 trips/year while the flyer might make 5/year......
