Rotor is the Boogie Man.

In the Air Force flight training they showed us movies of a B-52 whose
vertical tail had been torn off in an encounter with rotor. I feared
rotor, too, until encountering it for the first time /in a glider/ with
the airspeed well within the green arc. Yes, it's bumpy, but
maintaining control is a non-event. Using rotor to climb into the wave
is sometimes the only way to get there. There's a terrific mix of up
and down but, if you stay on the upwind side of the rotor, the net is
up. You climb in rough air and then, all of a sudden, it becomes silky
smooth and the rate of climb increases rapidly. What a treat! Having
said that, I still have enough sense not to fly through rotor with the
airspeed in the yellow!
