The shortest path to the Internet for some remote corners of the world may be through the skies. That is the message from US tech giants seeking to spread the online gospel to hard-to-reach regions. Google took a step in that direction this week with the acquisition of Titan Aerospace, a maker of solar-powered drones that can help boost Internet access to remote areas. “It’s still early days, but atmospheric satellites could help bring Internet access to millions of people, and help solve other problems, including disaster relief and environmental damage like deforestation,” said a Google spokesman. Titan’s drones are able to run for five years at an altitude of some 65,000 feet (20,000 meters).
