WATCH: Drone interrupts Ram-Dimitrov match in Delray Beach

When Drones Attack? Not quite. But on the same weekend that a retired U.S. military general called on the country's leaders to "embrace" drone warfare, one such small-scale flyover briefly delayed Rajeev Ram's semifinal victory over Grigor Dimitrov at the Delray Beach Open.

"That doesn't have anything to do with our broadcast or our team," Tennis Channel commentator Leif Shiras said at the time, "but just wondering if there's some sort of implied threat from this if it falls out of the sky."

Chair umpire Simon Cannavan stopped the match, and both players joined him at the net to survey the scene. Officials are likely on high alert for the possibility of such incidents after a drone crashed into the stands, hurting no one, during a 2015 U.S. Open match between eventual champion Flavia Pennetta and Monica Niculescu.

"Well, the French Open had, you know, I think it's falcons that they hire to keep other birds away," Shiras added. "Maybe they need something like that here in Delray Beach."

It sort of makes one miss the days when you feared bird droppings—not airborne multimedia equipment—potentially falling on you.

You can catch another look at said drone fleetingly at the 4:42 mark of this match highlight video:
