Accident rates are nothing to be happy about though, flying a helicopter is a lot harder than flying a light plane and flying into an obstacle or having something fail resulting in a crash are all too common. Helicopters are quite delicate compared to planes as well and even though they can usually auto-rotate that's better described as a controlled crash than an emergency landing.
Personally I'd never ever want to be in one of these but compared to a wingsuit they're probably safer.
