since the early 80's I've always remembered being taken to the end of the runway at Newcastle on Tuesday mornings during the school holidays to see both the CP Air and Wardair 747's operating to Toronto at around the same time. But, I've never seen a picture since of them both on the ground at the same time so could be wrong! However by1986 (when my real interest began) wardair holidays used wardair 747's and globespan used worldways Canada dc8's from Ncl to yyz.
