Cabin crew on a Turkish Airlines flight celebrated the arrival of anextra passenger at 42,000ft (12,800 metres) when a woman gave birth to a baby girl.
Passengers also assisted at the birth, which took place soon after take-off on a flight from Guinea's capital Conakry to Istanbul via Ouagadougou.
The mother and baby, named Kadiju, were taken to hospital when the Boeing 737 landed in the Burkina Faso capital.
Both are now reported to be tired but in good health.
"The cabin crew noticed that a woman passenger named Nafi Diaby, [who was] 28 weeks into her pregnancy, was suffering childbirth pains," a Turkish Airlines statement said.
