Coppi:
Are you telling me that if I were on a flight from JFK to LHR and Gander told me at 30 West that LHR was closed, I should go back to JFK?
Sorry son, I will keep going and discuss with the next authority (Shanwick) of the options such as Shannon, Dublin, Belfast, Manchester, Prestwick, Stansted, Machrihanish (just to show you that I can spell it) etc etc.
You don't know what you are talking about.
