Turkish Airlines' CEO Temel Kotil told newly-trained pilots to tie the knot to avoid another Germanywing tragedy.

Kotil, who addressed 86 newly trained pilots at a pilot training center in İstanbul on Thursday, said that last month's plane crash of Flight 4U 9525 in France “taught” that an airline pilot's duty is critical.

"Our pilot friends, whether they are men or women, their lifestyles are very important," he added. "Therefore, dear friends, we are absolutely encouraging those of you who are single to marry."

Germanwings co-pilot Andreas Lubitz locked the pilot out of the cockpit before intentionally crashing the plane into a mountainous region of southern France, say investigators.

Prosecutors are still looking into Lubitz's possible motives. Initial findings indicated he had previously been treated for depression and suicidal tendencies and reportedly told his girlfriend that he was planning a spectacular gesture that everyone would remember.
