Hawk-eyed Danica looked up from her handlebars and spotted a peculiar-looking helicopter hovering above the trees. I thought it was a full size machine, but quite far away. Danica got it right.
It was a model drone helicopter, maybe 2 feet wide, six propellors and steady as a rock. The guy flying it said it did have a camera. His control over the relatively quiet, battery-powered machine was very precise. I’ve seen many dog walkers with less control over their little dogs. Mr. Chopper literally walked his helicopter home, crossing a street and navigating between parked cars.
