Facebook completed successful test of solar-powered plane called Aquila, Mark Zuckerberg wrote.

The plane will beam internet to remote parts of the world and eventually break the record for longest unmanned aircraft flight. The flight took place in Arizona on June 28.

“We gathered lots of data about our models and the aircraft structure -- and after two years of development, it was emotional to see Aquila actually get off the ground.

But as big as this milestone is, we still have a lot of work to do. Eventually, our goal is to have a fleet of Aquilas flying together at 60,000 feet, communicating with each other with lasers and staying aloft for months at a time -- something that's never been done before,” Zuckerberg wrote.
