I may have found out what that experience is like, but luckily a friend who had just bought a drifter and was looking at my aircraft for similarities noticed that my left rudder cable had frayed to a point where there were only 2 out of six strands holding the cable on. The how or why isn't important but the second set of eyes is.
Norm Turner who was the CFI of our club always used to have a peek at other folks aircraft and it is this professionalism that keeps people alive. I welcome people having a look and pointing out potential or existing problems with my drifter because it helps keep me alive.
Anyway I put together a small video to show you what the cable looked like...
I have purchased like cable for both sides so I know that both rudder cables have the same life in them.
