Two Northwest Airlines pilots who overshot their destination by 150 miles before turning back should have had numerous warnings as they approached and passed Minneapolis: cockpit displays, controllers trying repeatedly to reach, the city lights twinkling below.

Yet the pilots didn't discover their mistake until a flight attendant in the cabin contacted them by intercom, said a source close to the investigation who wasn't authorized to talk publicly and spoke on condition of anonymity. By that time, the plane was over Eau Claire, Wis., and the pilots had been out of communication with air traffic controllers for over an hour. picked by cecilberman 1 month ago
