The news comes as a bit of a surprise that Facebook is planning to buy the Titan Aerospace company which makes solar-powered drones which have the surprising ability to stay up in the sky for as long as five years. Techcrunch's sources have revealed that Facebook will make use of the solar-powered drones to deliver sky-based internet access and with this comes the vision of developing at least 11,000 UAVs to deliver data services, initially, in Africa at least. Though we can't say much about whether the deal has been confirmed or not but the drone did confirm having discussions of this nature with Facebook.
This is the only way in which the social network's Internet.org efforts to expand online access in developing countries will come to surface. It seems like Facebook is taking the lead of Google which is also trialling internet access from the sky but instead of drones they are making use of balloons with the help of Project Loon. If Facebook decides to continue with this deal, then it will cost $60 million which is nothing compared to what an app might cost.
