Facebook Chief Executive Mark Zuckerberg announced a successful first test flight of his solar-powered internet drone, Aquila, on Thursday. The test flight took place in Yuma, Arizona and the drone was aloft for 96 minutes, while it was expected to be aloft for only 30 minutes. The concept of the drone is that as it circles a region, it will use laser-beam technology to deliver internet to those within a 60-mile radius. To do this successfully, the aircraft must fly 60,000 feet or more above the earth. With a wingspan of a Boeing 737, Aquila faces many engineering challenges before it can provide affordable internet to those without easy access. For instance, it must be able to collect enough energy during daylight hours to operate for 24 hours a day. It must also have batteries that can efficiently store enough energy for as long as 3 months at a time. Under Project Loon, which uses high-altitude, wind-propelled balloons, Google parent company Alphabet Inc. is also in the race to bring internet access to everyone.
