Facebook says it will begin test flights later this year for a solar-powered drone with a wingspan as big as a Boeing 737, in the next stage of its campaign to deliver Internet connectivity to remote parts of the world.
Modern mountain climbers typically carry tanks of oxygen to help them reach the summit. It's the combination of physical exertion and lack of oxygen at high altitudes that creates one of the biggest challenges for mountaineers.
A newly declassified CIA document confirms the existence of famed Area 51 in Nevada, but conspiracy theorists will be disappointed the spy agency offers no proof of alien spaceship landings in the desert.
