"Quote:
CVR data has been read. It seems structural failure (windshield? not determined yet)..It was quick... sound of cracks,but crew initiated emergency descent by autopilot and then they weren't heard anymore. Autopilot was on during whole descent, but disconnected automatically shortly before impact when GPWS alerts appeared."
