Mashable says "Facebook's drone prototype has wingspan greater than a Boeing 737"

Facebook revealed new details on Thursday about its plan to bring web connectivity to the 4 billion people worldwide without Internet — and it's banking big on drones.

During a keynote at its annual F8 Developer Conference in San Francisco, the company showed photos of a solar drone prototype it is working on to bring Internet access to rural areas.

According to Facebook's chief technology officer, Mike Schroepfer, the final design of Facebook's V-shaped drone prototype will have a wingspan greater than a Boeing 737 and the mass greater than a small car.

The unmanned aircraft, which beams Internet access to people on the ground below, has already completed its first test flight in the U.K., CEO Mark Zuckerberg "noted on his Facebook page.

"It will be powered by solar panels on its wings and it will be able to stay at altitudes of more than 60,000 feet for months at a time," Zuckerberg said. "Aircraft like these will help connect the whole world because they can affordably serve the 10% of the world's population that live in remote communities without existing internet infrastructure."

The prototype's codename is Aquila after the eagle in Greek mythology who carried Jupiter's thunderbolts.

"We are investing in radical new approaches to this problem... and we are going to the sky," Schroepfer said. "This is one of many initiatives we are doing."

The details comes just one year after Facebook announced it was building drones, satellites and lasers to deliver the Internet to everyone. The move is a part of a greater effort to support the Facebook-led initiative, which is already bringing free Internet data to four African countries, Colombia and India.

The company also announced during the keynote that the Facebook-owned Oculus Rift will officially launch "this year." The move could catapult virtual reality gaming into the mainstream.

"You're going to be able to do it in something shipped by Oculus," Schroepfer said. "This is going to be incredible."
