Somewhat, but not entirely, facetiously, I wonder if we'll soon see some sort of earthbound device to shoot down tiny drones. Tiny surface-to-air missiles seem like they'd be too costly and a bit heavy handed anyway. Maybe a radar-guided laser device?
Drones may seem like a fun hobby-like gizmo now. But I think they will quickly become the focus of public ire depending on their size, sound, capabilities, and purpose.
I like the idea of adding a crotchety person with a broom to the obstacles! But seriously, I wonder if a magnet is really the best device to pick up a flash drive...? First, not all drives would respond to a magnet. And second, could magnetism damage the files on the drive?
Now that FAA has approved some drones to fly over US airspace, general public might watch this competition closely to see what to expect of the latest drone models. To say the least, what will the future bring? Drone swatting devices, like brooms, could be very useful.
