Yes, true.

Helicopters can glide also, sort of. Autorotation is the way you can still land when you have a complete engine failure in a helicopter. You harvest the remaining energy in the rotor for one last landing.

I guess a crude analogy would be, you immediately put it into neutral, then throw it into reverse at the right moment.

In the best case scenario, it's safer to lose your engine in a helicopter than an airplane, because at least you get to choose your landing area, and you aren't landing with 60 knot forward speed.

IANAP, just an enthusiast so grain of salt.

One of the best uses of sound in film. Everything Walter Murch does is amazing.
