Why drone hysteria has taken off

Dating back a month now, you've either seen them in the sky, or you've seen them on the news: Drones seem to be everywhere. By all accounts, alleged drone sightings are multiplying exponentially, with more than 5,000 reported in just the past few weeks alone.

But of those 5,000, only a hundred or so have generated actual law enforcement leads.

George Mason University engineering professor Missy Cummings, who has been doing drone research for 25 years, says what most people are actually seeing are likely aircraft, stars, or reflections off of objects, like towers. "Of all of those options, drone is the least likely, because it's actually pretty hard to pick these out of the sky," she said.
