At least two of Northwest Airlines pilots won’t have to worry about crew scheduling now that the government has clipped their wings after they flew 150 miles past their destination. The Federal Aviation Admin­istration has revoked the licenses of pilots Timothy Cheney of Gig Harbor, Wash., the captain, and Richard Cole of Salem, Ore., the first officer, after the pair told investigators they were working on their personal laptop computers on flight-crew scheduling while flying a jet with 144 passengers from San Diego to Minneapolis. The jet was out of radio communications with air traffic controllers for 91 minutes, despite repeated efforts to contact the pilots. The pilots said they weren’t listening to the radio or watching flight displays as the plane was on autopilot. That’s totally unacceptable, and the FAA is right to move to revoke their licenses, saying their actions were a dereliction and disregard of their duties.
