A Korean Air flight from Vancouver to Seoul was forced to make an emergency landing at a Canadian Air Force base after someone called in a bomb threat yesterday, reports the CBC. The flight, which was carrying 134 passengers, was accompanied by American F-15 fighter jets as it rerouted to the Comox air base on Vancouver Island, about 110 miles northwest of Vancouver. It was the second bomb threat in two days to the same flight after an earlier threat was made before the flight took off on Monday. Police found no evidence of a bomb either time.
