UPDATE.... From CBC News The airline is blaming a mechanical error for the false hijacking message. Officials say the plane's crew cannot get the transponder signal to stop. However, as a precaution, the North American Aerospace Defence Command sent Canadian fighter jets to intercept the aircraft over the Atlantic. The Norad jets are escorting it to its new landing site. Initially there were conflicting reports on where the flight would land. First it was being sent to Moncton, N.B., but then reporters were told it might land in either Newfoundland or Nova Scotia. Halifax was later confirmed as the intended landing site. MORE.....
