Vern Conaway was watching a YouTube video when he first realized he would have to start paying attention to drones.
The vice president of public safety and security for the Maryland Stadium Authority—responsible for both Camden Yards and M&T Bank Stadium—found the video shortly after it was uploaded in 2014. It showed footage of Baltimore, taken by a drone flying over the city’s inner harbor before heading in the direction of Camden Yards, close enough to show a packed stadium with players on the field mid-game. It didn’t fly directly overhead, so it had not been noticed at the time, but it came fairly close.
