Malaysian Airlines Flight MH17: data recovered from cockpit voice recorder

Dutch Safety Board officials said Wednesday the black box recorders from Malaysian Airlines Flight MH17 are damaged, but at least one of their recordings is intact.

The two flight recorders, which were recovered by pro-Russian separatists after the Boeing 777 was downed last Thursday in Eastern Ukraine, were given to Malaysian authorities on Monday. They were then sent to the Air Accidents Investigations Branch, a lab certified by the International Civil Aviation Organization in Farnborough, southern England, for analysis.

"The cockpit voice recorder was damaged, but the memory module was intact,” the Dutch Safety Board, which is now leading the investigation, said in a news release.

"No evidence or indications of manipulation of the cockpit voice recorder was found. Following the examination, the cockpit voice recorder data was successfully downloaded and contained valid data from the flight.”

The flight data recorder has yet to be examined, but will be checked on Thursday, the Dutch officials said. If it’s usable, the data from the two recorders will be combined.

It’s unclear what can be gleaned from the recordings, but investigators are hoping for some definitive clues as to what brought down the plane. Ukrainian and American officials have both strongly suggested Flight MH17 was brought down by a missile.

Dutch Safety Board officials said analyzing the data will take time.
