The leader of the Russian plane crash technical investigate committee has told reporters that data from the jet’s cockpit voice recorder has been downloaded. A “noise” can be heard in the last moments of the recording. He said the nature has not yet been determined. <br /><br /> The flight data recorder revealed that the plane’s autopilot had been engaged until the end of the recording, 23 minutes 14 seconds into the flight. <br /><br /> He explained that the information is still in the “information gathering” phase and said debris from the plane was scattered over a 13 kilometre area, which is consistent with an in-flight break-up. <br /><br /> Initial observations do not allow investigators to draw any conclusions about the cause of the crash.
