MOSCOW, Dec. 21 (UPI) -- The Russian fighter jet shot down by Turkey has yielded a flight recorder box with mostly unreadable data, investigators revealed Monday.
Russia had hoped evidence within the so-called black box of the Su-24 plane, downed Nov. 24, would prove the aircraft never passed through Turkish airspace, but Sergey Bainetov, deputy chief of the Russian Air Force flight safety service, announced 13 of the 16 recording microchips aboard the plane were damaged beyond use. One may be adequately preserved to obtain data, he said.
