Regrettably, the problem may be cultural. The Capt. was possibly a smug ex-Turkish Air Force pilot, and the F/O and jumpseat were suitably subservient, to the point of watching death approach, but too scared to object (fearing pointing out dangers would cast doubt on the Captain's Command Authority). The Turkish culture is rich, but, aviationally speaking, much to deferential to authority. Maybe I am pre-mature, but I see no other explanation now. This is an inherent weakness in Turkish culture.
