Unless I have missed a trick here. The lack of announcement from the Captain to the pax(and by the sound of it cabin crew) until arrival in SNN is truly appalling. A go around and divn is nothing unusual to any aviator and am sure it was flown and carried out in a professional manner. However as a trainer, in my company I would have failed the Captain on a line check for his lack of communication to pax and cabin crew alike. Unless of course his lack of action can be justified and I cant think of a reason following a NORMAL go around and divn.
