Helicopters aren't that safe. Helo pilots are in denial because they drank the kool-aid. Their "failsafe" of autorotation doesn't work without enough forward airspeed and doesn't do any good for crashes while at or near hover or severe loss of control. Then you have the massive number of pending single point failures in the mechanical hardware. You are at the mercy of the engineering and maintenance far more than in an airplane.
Here's a rare survivable crash from low altitude[1]. The passengers still suffered serious injuries. Here is an autorotation training landing[2]. How often will this be possible in real life when something is broken? Here's a failed autorotation with RPMs too low like might be encountered with engine power loss [3].
I can believe that autorotation landings are dangerous, but then, so are airplane engine-out landings at night over water... but how often are they necessary?
Helicopters are more dangerous than other aircraft:
The crash rate for helicopters alone is 9.84 per 100,000 hours. That means helicopters crash about 35 percent more often per hour in the air than your average aircraft
But have a lower fatality rate:
The fatality rate in helicopter crashes is 1.3 deaths per 100,000 flight hours versus 1.4 deaths for aircraft in general.
