jimjim1, thanks for the 360 degree Airbus link, and especially for the pic
recreating the jammed camera scenario. If ever there was a case of one picture versus a thousand words it is surely that one!
Interesting too that the final recommendation was:-
If possible, implement measures that could help prevent the placing of loose articles in close proximity to the side-stick.
Prevent is probably impossible. Actively discourage by training and appropriate marking aft of the side stick far more achievable I'd suggest.
