There are an estimated five billion people worldwide who lack reliable internet access but Facebook is reportedly "ready to spend billions" in order to change that. The Menlo Park-based company has recently announced plans to deliver global connectivity on the backs of enormous, solar-powered UAV, dubbed project Aquila. The plan is still very much in its initial planning stages but Facebook appears to be dedicated to making it a reality. Facebook acquired UAV maker Ascenta last year as its in-house drone design team and has already set them to work developing a platform capable of spending up to three months aloft while cruising at altitudes between 60,000 to 90,000 feet. Each UAV is expected to have a wingspan rivaling Boeing 767 (about 156 feet from tip to tip) but only weigh about as much as a Kia.
