Moscow: Russian crash investigators say they have found a tape of cockpit conversations from a Boeing 737 that slammed into the ground in a nosedive crash, killing all 50 people on board.
The voice-recording tape, missing when its container was found earlier, was located by search teams today.
Systems data retrieved from another onboard black box allowed the Moscow-based Interstate Aviation Committee to conclude that the crew lost speed in a steep climb, then overcompensated and sent the plane into a near-vertical dive.
It said all the plane`s systems were working normally until the moment it hit the ground and exploded in a giant fireball.
The Tatarstan Airlines plane was flying from Moscow to the central city of Kazan, 720 kilometres to the east.
