In 1982, Northrop quietly flew a stealth aircraft so radar-invisible the U.S. Air Force later said its radar cross-section was smaller than a bat's. The Tacit Blue "Whale" pioneered the curved-surface ...

For all their environmental appeal, wind turbines have few fans in the military or among air traffic controllers. Strange as it might seem, radar systems easily confuse the turbines’ rotating blades ...
