EgyptAir black box 'located'

Egyptian government sources are telling CBS News that they have located Flight 804's black boxes in the Mediterranean and are working to recover them. A military spokesman refused to comment on the report, The Telegraph reports.

If that is confirmed - and there have been several false starts so far - it would be a major step forward in figuring out what happened to the flight. 

The two data recorders, as long as they are intact, will tell investigators what was said in the cockpit in the plane's final minutes and will record data about the aircraft's final movements.
