Create a scene where an advanced, futuristic flying machine hovers effortlessly in the sky. The machine should have a sleek, metallic design with glowing elements, such as blue or white lights accentuating its contours. It should emit a soft hum or gentle thrumming sound as it floats in mid-air. The background shows a clear sky with soft clouds drifting, and distant mountains or cityscapes below. The flying machine moves slowly, demonstrating its advanced technology and stability in flight. Capture a sense of weightlessness and precision in its hovering movement.
