As an ex TEV Canberra Engineer that photo of the Bogey at Gadana beach is soooo sad.
Reference getting troops down there (or anywhere else!) by ship. As others have referred to there are no British companies left, Cunard has not been British owned for years however P&O was always a British Government "golden shares" company to ensure that ownership could never pass abroad for reasons of National security...I could never understand how that was allowed to change.
Incidentally with the exception of the QM 2, modern cruise ship design is vastly different form the line voyage days of the Canberra and Black Pig (even if she was a complete wreck and deemed too unreliable to actually go near the Falklands!) Would be interesting to see a modern ship trying to keep the revs up in a big sea if it was deemed necessary.
