Rescue Helicopter EC 145 Takeoff Sound

In this audio, the unmistakable sound of a rescue helicopter, specifically the Eurocopter EC 145, taking off dominates the scene. The intense, rhythmic whirring of the chopper's blades cutting through the air can be heard gradually increasing in speed and volume, indicating the lift-off.
