Despite recent setbacks in India, Facebook CEO Mark Zuckerberg is still pushing on his goal to connect the world through his philanthropic organization, Internet.org. A large part of that vision rests on a drone infrastructure to fly over remote locations and beam internet access down to the ground.

These drones, called Aquila (plural being Aquilas?), will fly in tight loops around areas with little or no access to internet, according to Yael Maguire, head of Facebook's Connectivity Lab.

Today, Zuckerberg wrote that Facebook has been flying prototypes of its drones every week, and the company is in the process of building a full-scale aircraft for a larger test.
