Flew on a KLM DC8 combi, once. Don't recall any shimmy, but, do recall the departure and climb seemingly tried to emulate a Lightning ...I was impressed !
However, came back from YVR on a CP Air DC10...which happily gently rolled both ways in an almost controlled manner. I thought this was possibly due to an A/P roll channel problem, but, maybe it was due to the reasons others have mentioned.
More memorable for being a clear, moonlight night, looking down and seeing large areas of white, with the occasional cluster of lights, and hence the vastness of Canada displayed.
