Investigators have found the missing cockpit voice recorder of a crashed Cypriot airliner in which all 121 on board died, Greece's state-run television NET reported. Seachers had initially discovered the outer box of the cockpit voice recorder and the Helios Boeing 737 plane's flight data recorder or "black box" shortly after the plane crashed Sunday near Athens while on a flight from Larnaca in Cyprus to Prague. "The second black box voice recorder has been found near the wreckage of the tail section of the plane," NET was quoted by dpa as saying. Investigators hope the recorder's last 30 minutes of conversations in the cockpit will shed light on why both the pilot and co-pilot, as well as many passengers, were left unconscious during the flight. --More 1328 Local Time 1028 GMT
