Facebook ready to test giant drone for internet service

Facebook says it will begin test flights later this year of a solar-powered drone with the wingspan of a Boeing 737, the next stage of its campaign to deliver Internet service to remote parts of the world. Engineers at the giant social network say they've built a drone with a 140-foot wingspan that weighs less than 1,000 pounds. It will use lasers to send Internet signals to stations on the ground.
