It is indeed very sad to see it go.
I remember my most memorable experience with the DC-10 is when they were still CP Air, I flew between YVR-HKG, that flight was delayed for 11 hours due to mechanical problems. We had takeoff attempts before they finally announcing the delay of the flight. CP gave us hotels and meals for the night. When we landed in HK, the whole plane actually applause.
Other memories in the recent days about DC-10 is that they are very hard to get upgrades on!!
Let's look on the bright side though... hopefully retiring the DC-10s will save CP some money. It'll even be sader to see the whole company go. One of the reason I am against Onex, happy to see them back off.
I guess we should enjoy them while they are still around. I think they are using them to fly YYZ/YVR - HNL now instead of the 767s.
