Sitting on board the Maersk Delft, waiting to depart Dover docks, passengers stare as the huge MSC Armonia glides into dock, flash bulbs glinting as passengers get the obligatory shot of the not-so-white Cliffs of Dover. As the ferry finally moves off from the quay, only a few minutes late, some wag plays Ride of the Valkyries on the entertainment system. Hmm, slightly fanciful thinking, I feel.
