Walter can be seen wearing gloves as he leaves the helicopter.
When he sees the helicopter, Sylvester states "Helicopters have zero aerodynamics and no glide ability in case of engine failure."
Per the FAA Helicopter Flying Handbook: Autorotation. In a helicopter, an autorotative descent is a power-off maneuver in which the engine is disengaged from the main rotor disk and the rotor blades are driven solely by the upward flow of air through the rotor. In other words, the engine is no longer supplying power to the main rotor.
So Helicopters are fully capable of a gliding type ability in autorotation, to make a safe and controlled landing in the event of engine failure.
