Facebook takes to the skies

Facebook says it has completed a successful test flight of a solarpowered drone that it hopes will help it extend internet connectivity to every corner of the planet.

Aquila, Facebook’s lightweight, high-altitude aircraft, flew at a few hundred metres for 96 minutes in Yuma, Arizona, chief executive Mark Zuckerberg wrote in a post on his Facebook page.

The company ultimately hopes to have a fleet of Aquilas that can fly for at least three months at a time at 18,290 metres and communicate with each other to deliver internet access.

Google parent Alphabet has also poured money into delivering internet access to underserved areas through Project Loon, which aims to use a network of highaltitude balloons to made the internet available to remote parts of the world.

Yael Maguire, Facebook’s engineering director and head of its Connectivity Lab, said that the company initially hoped Aquila would fly for 30 minutes.

‘‘We’re thrilled about what happened with our first flight,’’ Maguire said. ‘‘There are still a lot of technical challenges that need to be addressed for us to achieve the whole mission.’’ He said he hoped the system might be brought into service ‘‘in the near future’’.

Zuckerberg laid out the company’s biggest challenges in flying a fleet of Aquilas, including making the plane lighter so it can fly for longer periods, getting it to fly at 18,290m and creating communications networks that allow it to rapidly transfer data and accurately beam down lasers to provide internet connections.

Maguire said Aquila will go through several more test flights and hopes it will soon break the world record for the longest solarpowered unmanned aircraft flight, which currently stands at two weeks. Reuters
