Son Flies.
Son takes parents for ride with instructor.
Be me, back seat.
Engine goes quiet.
WTF????
"Autorotation" they say.
Parents look at one another.
Obviously something wrong with engine.
Landing helicopter without engine.
Cant say crap.
Dont want to disturb son.
Especting possible crash.
Son picks car size parking space to land.
Lands beautifully.
Instructor calls him show off.
Parents finally told meaning of autrotation.
It's a constant mandatory exercise.
Heart attack city, but, helicopters handle pretty well without engine, it is true.
Now, parent wants to go on THIS ride (vid related)
