NEW YORK (Reuters) - A New York childrens author who used a curse word in exasperation during a plane delay at a US airport was ejected from the aircraft for disruptive behaviour. Robert Sayegh, 37, said Atlantic Southeast Airlines overreacted to his salty language when it summoned police aboard to escort him off the Sunday evening flight at Detroit Metro Airport. The f-word is not a nice word to use, he acknowledged in a telephone interview, adding he was complaining to himself rather than snapping at anyone in particular. I really didnt think I was being that loud. Sayegh, who is also a television producer, was catching a connecting flight home after attending a relatives wedding in Kansas City, Missouri. He was, by his own account, feeling tired. I said the f-word, Sayegh said.
