The Australian-British citizen aboard the missing EgyptAir flight is believed to have been as a geologist who had become a father for the second time in recent weeks.
Richard Osman, 40, was said to have been “deliriously happy” at the birth of his daughter Olympe.
Born at the end of April, Olympe was Mr Osman’s second child with his 36-year-old French-born wife Aurelie.
