Federal investigators say pilots who were killed when their UPS cargo plane crashed during a landing attempt in Birmingham, Alabama last year made a series of errors, and may have been suffering from fatigue.
But the investigators also conclude that more stringent regulations on hours of work for pilots wouldn't have prevented the accident.
Investigators are telling the National Transportation Safety Board Tuesday that the pilots of Flight 1354 incorrectly programmed the plane's flight management computer, descended too fast, failed to call out altitude levels and didn't abort the landing when they realized they weren't lined up properly.
