The last AC
flights flew YVR
on October 24, 1970, using Viscount aircraft.
took over the route on October 25, 1970. The type is noted in the timetable as T-prop, so I am assuming it was with CV640 aircraft. The only other turboprops at PW
at this time were the Electra and the Hercules, not likely on this route.
Just because I stopped arguing, doesn't mean I think you are right. It just means I gave up!
