Flight 447 Report Pushes Black-Box Changes

The experts investigating the crash of Air France Flight 447 have recommended in a new report that the black boxes used by investigators to determine the cause of a crash should be changed to signal for a longer period of time. The investigators have still not been able to find the black boxes from the Paris-bound plane, which departed from Rio de Janeiro on June 1 and crashed shortly after in the Atlantic, killing all 228 on board. Currently, black boxes emit signals for 30 days, which the report's authors say is not enough time for search operations; instead, they recommend that the signal continue for 90 days. The authors also recommended that transoceanic aircraft be outfitted with another black box, transmitting at a different frequency to aid search operations. In June, The Daily Beast's Clive Irving recommended even further changes to the black-box system.
