Eddie Mckay,a once-forgotten pilot,is a subject of great interest to a group of history students in Canada.
It all started when Graham Broad,a professor at the University of Western Ontario,found McKay’s name in a footnote in a book about university history. McKay was included in a list of university alumni (校友)who had served during the First World War,but his name was unfamiliar to Broad,a specialist in military history. Out of curiosity,Broad spent hours at the local archives (档案馆)in a fruitless search for information on McKay. Tired and discouraged,he finally gave up. On his way out,Broad’s glance happened to fall on an exhibiting case showing some old newspapers. His eye was drawn to an old picture of a young man in a rugby uniform. As he read the words beside the picture,he experienced a thrilling realization. “After looking for him all day,there he was,staring up at me out of the exhibiting case,” said Broad. Excited by the find,Broad asked his students to continue his search. They combed old newspapers and other materials for clues. Gradually,a picture came into view.
