Since helicopters can autorotate, they're actually safer in the event of engine failure.

  But only if it's high enough for the rotors to generate lift as it falls, there must be a death zone between 5m and 100m.

  I'm not so sure it's that simple. Airplanes can glide, autorotation is hard and rotors tends to break apart violently on impact.

  Helicopters can autorotate but I wonder what the statistics are for them doing so and landing safely?
