Facebook's Aquila drone takes to the air

Facebook has revealed that one of its solar-powered Aquila drones has completed a first test flight.

The trial, which took place above the US, is intended to ultimately lead to the creation of a fleet of internet-beaming aircraft that will make it possible for more people to get online.

The social network invited the BBC's technology correspondent Rory Cellan-Jones into its drone factory in Somerset, England to mark the occasion.
