Steering a ship by the stars fell out of favor with the rise of radio wave and GPS navigation. In fact, the U.S. Naval Academy stopped teaching the skill nearly 20 years ago. But now this ancient navigation is making a comeback at the Annapolis school, thanks to cybersecurity fears, according to the Capital Gazette.
"We went away from celestial navigation because computers are great," Lt. Cmdr. Ryan Rogers, the deputy chairman of the academy's Department of Seamanship and Navigation, told the Gazette. "The problem is, there's no backup." - via Andrea Peterson reporting at The Washington Post
