Helicopters suck when things go wrong. No gliding capability, just straight down. No real chance of escaping either. It appears from this video at least one person died. I pray for a miracle otherwise.
Auto-rotation is pretty impressive though. I've watched canadian Coast Guard pilots practice coming down without power, restarting just before hitting the ground and taking off over and over again. It seems to defy logic, but it's a thing.
That video did not feature auto-rotation.
You need sufficient altitude or sufficient forward speed to auto-rotate, this had the former but regardless a helicopter doesn't drop like this if rotors are in any way still spinning, could be blades were locked up(possibly one blade missing but it still wouldn't drop like this), which suggest something major mechanical be it deliberate or accidental(to be honest it almost looks like it is being driven into the ground...)
Not an expert by any means, but it's not entirely accurate to say "no" gliding capability, but how you can handle failures in a helicopter depends on how and when it fails.
Some types of helicopters are hybrid and have wings. This one in the video,....and by the way it came straight down, didn't have any gliding capability..
Manipulation of the collective using a lever will generally allow you to land without power. This allows you to use autorotation (as referenced above) to safely land in the event of engine or tail rotor failure.
The problem is when the main rotor has a critical failure.
