BEIJING, May 9 (Xinhua) According to foreign media reports, Menzio, a well-known Italian economics professor, was reported to be suspicious by female passengers in the same flight because he was writing calculus equations on a passenger plane, which caused an American Airlines flight to turn back after taking off. After he was questioned by airport security personnel, the plane was delayed for about one hour.

　　According to reports, Guido Menzio, a professor of economics at the University of Pennsylvania with brown skin and black curls, took an American Airlines flight from Philadelphia to Syracuse. A woman next to her later told the crew that she was not feeling well.

　　After the flight turned back, the woman got off the plane and said that the real reason why she wanted to turn around was that she was "very worried" about Menzio’s move.

　　The passenger said that Menzio scribbled casually in the notebook, which seemed to be a mysterious symbol. A spokesman for American Airlines said that the driver quickly decided that "the female passenger’s doubts were not established".

　　After Menzio met with airline security personnel, they said that he was suspected of "terrorism".

　　Menzio showed them his graffiti, saying that it was actually a calculus equation.

　　Menzio won the Carlo Alberto Medal for the best Italian economist under 40 last year.
