And the skill level required to operate it was, according to the owner, minimal.

A friend of mine had a remote-controlled helicopter about 20 years ago which was about impossible to fly and land. He had a computer simulator for it, and I couldn't fly the darned thing.

This one had a controller much like a game box which could control everything, or it could be told where to go and it would. Many of the flight characteristics such as yaw and pitch seemed to be controlled by an onboard computer and sensors. The guy running it would tell it to go up, or over there and it would.

The uses are unlimited, but maybe not essential. I sort of regard the thing like email. I didn't know what use it might be when I first heard of it.

Anyway, it was a fun toy to watch.
