DaveReid - Yes, I flew on an Air Canada DC8-61 London/Montreal. The difference between that and the Caledonian 757 was that I was expecting a standad BA 3-cabin 757 and was very surprised by what I actually saw. Such was my surprise that I made a comment along the lines of "Oh my God a Cally 757" and the crew member standing next to me replied "How do you think we feel"!
