The Extreme Drone Racing Circuit returned to downtown Las Vegas Saturday.
The event, head at Zappos Headquarters, features more than 60 drone pilots from around the world competing head to head for $10,000 in cash purse and sponsorships.
Organizers called it the world's most challenging course. Drone pilots race by guiding their drone using special video goggles that allow them to see the race from the drone's perspective.
