When I was spotting at YYZ past midnight one day in the last week of august, I saw the Roots Air 727 land, I think. So evidently being used for something. Freighter, I guess? Anyway, as for DC-8's, when I was sitting in Terminal 3 early in the mornign of June 23rd, waiting for my C3/CJ flight to YHZ, I looked out the window and was surprised to see an Emory DC-8! It was the first DC-8 i'd ever seen SINCE I became an aviation fan (wouldn't have recognized it when I was younger), and it was quite a nice surprise. It looked really good. From far away head on, I thought it was an A-340!
Next flight.... who knows.
