From the article:
"Gray Brooks had a drone crash land in his backyard in Washington, D.C. last year. He and his girlfriend were a bit freaked out by it but acted rationally. They held a piece of paper with their number on it in front of the drone’s cam… and then covered the drone with a pot so that it 1) wouldn’t fly away, or 2) keep spying on them."
"The dr-owner turned out to be their neighbor. “The first thing he showed us when he knocked on the door was the photo on his smartphone,” says Brooks."
