Individuals familiar with the investigation of the crash of Air France Flight 447 are pointing to sweeping computer outages as a possible cause for the crash. Because modern aircraft are highly automated, pilots may have little experience in overriding faulty systems, according to some experts. Such outages, though rare, can pose a "real threat," according to Bill Voss, president of the Flight Safety Foundation. "We need to examine how to deal with automation anomalies." Investigators continue to search for the plane's black boxes, and stress that it is still too early to definitively pinpoint causes of the accident.
