Hungry? Look up in the sky - there could be a pizza over your head right now!

You can call it pie in the sky, but pizza delivery is now a real thing -- at least in the Land Down Under.

Domino's Pizza Enterprises said Wednesday it had completed what it called the world's first delivery of a pizza to a customer in New Zealand. Under the watch of a team of drone experts, the unmanned aerial vehicle used GPS navigation to autonomously deliver Peri-Peri Chicken and Chicken and Cranberry pizzas to a backyard in Whangaparaoa, about 20 miles north of Auckland.

Drones have grown in popularity among big retailers such as Amazon and Walmart, which are continually looking for new ways to get a jump on the competition and attract customers. The small, commercial aerial drones could avoid the delays of terrestrial deliveries by flying above traffic and avoiding circuitous roadways.

"They can avoid traffic congestion and traffic lights, and safely reduce the delivery time and distance by traveling directly to customers' homes," Domino's Group CEO Don Meij said in a statement. "This is the future."

Domino's plans to use the information gathered from these flights to expand the service to Australia, Belgium, France, The Netherlands, Japan and Germany.
