"Flying between 60,000 and 90,000 feet, Aquila uses lasers to transmit data to other aircraft as well as receivers on the ground that then convert signals into internet access."
"For Facebook, Aquila is more than a proof of concept. It’s a linchpin of the company’s plan to bring the internet to all 7 billion people on Earth, regardless of their income or where they live. Doing so will lift millions of people out of poverty, Zuckerberg says, improving education and health globally along the way. But it will also enable the next generation of Facebook’s services in artificial intelligence, virtual reality, and more. This next era of tech will require higher bandwidth and more reliable connections than we have today, and drones can help deliver both. The road to a VR version of Facebook begins where Aquila leaves the runway." - The Verge
