A sound like a swarm of angry bees

We had an interesting new device come with Gordon
(Sam's fiance) last weekend.

He had bought a new drone for business and it was very
exciting to watch. Flashing lights, sounds, and deft movement.

 Here is the camera.

 Viewing from a computer screen.

 Looking at our immediate neighbourhood.

 It can fly to 120 metres.

 Hovering over the pool it displaces water strongly.
