What did you do with your weekend? 15-year-old Luke Bannister just won $250,000 by beating out 150 teams in the first World Drone Prix, held in Dubai. Drone racing is now a very real thing, with racers using camera-mounted navigation to steer their craft around a track -- and through or around obstacles. Even if you didn't place first, the Drone Prix offered a prize pool totaling $1 million.
