Growler:
Sorry, old boy, but it seems that they did'nt have the problem sorted, as they were referring to themselves as "Mayday BRT 903" all the way to MAN, and squawking A7700. They repeated that they were still having control difficulties on a number of occasions after they decided to divert to MAN.
Now, if they had the problem sorted, they would have cancelled the MAYDAY, "Full Stop", to quote your goodself, wouldn't they?
