Leave Us Alone; We're Busy

WASHINGTON - Federal investigators are scrambling to determine what happened aboard a Northwest Airlines jetliner whose crew flew 150 miles past its destination while air traffic controllers, other pilots and even a flight attendant back in the cabin tried to get their attention.

Investigators don't know whether the pilots may have fallen asleep, but National Transportation Safety Board spokesman Keith Holloway said today that fatigue and cockpit distraction will be looked into.

...The crew told authorities they were distracted during a heated discussion over airline policy, the NTSB said.

Wednesday night, the airliner with more than 140 passengers aboard zoomed past Minneapolis at 37,000 feet at what was supposed to be the end of a flight from San Diego. Worried about who was actually at the controls, officials asked the crew to prove who they were by executing turns after they finally were contacted.

On the ground, police and FBI agents prepared for the worst, and the Air National Guard put fighter jets on alert at two locations as the drama unfolded.

Pilots from two other planes in the vicinity were finally able to reach the pilots using a different radio frequency, a controllers union spokesman said. A flight attendant in the cabin also was able to contact 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 Airbus A320 was over Eau Claire, Wis., and the pilots had been out of communication with air traffic controllers for over an hour. They turned back and landed safely in Minneapolis, the plane's scheduled destination.
