[00:00:00]Engine failure doesn't mean death, the last magic trick of a helicopter.

[00:00:05]Helicopters and other rotary-wing aircraft have a [music] remarkable safety feature called auto rotation, which allows them to land safely even [music] if the engine completely shuts down. Under normal conditions, a helicopter's engine drives the main rotor, which pushes air downward to generate [music] lift. But here's the thing, if the engine fails, the main rotor itself stores a tremendous amount of rotational kinetic energy. [music] So while the helicopter loses its powered thrust, that stored energy keeps the rotor spinning, [music] allowing the aircraft to descend in a controlled manner rather than simply [music] falling out of the sky. And for the landing, the pilot pulls back on the controls, raising the nose at just the right moment, using [music] that last burst of rotor energy to cushion the touchdown and bring the aircraft safely to the ground.
