Regarding the side-stick priority issue, it should be remembered that the overall experience level of the RAF's Voyager aircrew was quite low at the time.
I presume that the (unlikely) case of a jammed side-stick was covered during training?
Given the amount of kit that the aircrew were obliged to take with them at the time, which was FAR more than that required by an airline crew, one wonders what guidance (or SOP) was in place concerning the placing of unrestrained objects in the vicinity of the side-stick...
As for 'mucking about' with a camera, dear weather-guesser, that's rather an unpleasant slur to cast...
