Microsoft is copying the soaring skills of hawks and eagles to build a glider that can stay in the air indefinitely, said Andrew Liszewski at Gizmodo. The self-piloted aircraft uses artificial intelligence to spot thermals, the rising columns of warm air that birds of prey use to stay aloft "for extended periods with minimal effort." The experimental craft — a model sailplane with a 16.5-foot wingspan — gathers data like air temperature and wind direction, to find the air columns and predict where the next one will be, keeping itself airborne without a motor.
