United Airlines says it was human error that caused a computer failure that grounded all United flights for two hours, snarling air traffic nationwide. From the Chicago Tribune:

“It was human error during routine testing,” United Chief Operating Officer Pete McDonald told airline employees on a recorded call. “An employee made a mistake and caused the failure of both Unimatic and our backup system.”

McDonald did not identify the person responsible, and United officials did not return calls seeking information on how the mistake occurred.
