Investigators recover the cockpit voice recorder .
The flight data recorder details the last moments of Egypt Air Flight 990. In a press conference Tuesday evening, NTSB chairman Jim Hall said his organization would work with the Egyptian government to further scrutinize flight data recorder and the cockpit voice recorder data over the next several days. According to Hall, the Egyptian government wanted the chance to send another set of experts to the U.S. to analyze flight data. The transfer would indicate the beginning of a criminal investigation into what caused the Boeing 767 to plummet into the Atlantic while en route from New York to Cairo Oct. 31. The crash killed all 217 people aboard.
