At about 3.00pm the Captain broadcast to passengers and crew to announce that a member of the crew was not well and needed to be airlifted by helicopter and taken ashore.
He told us to clear the decks and remain inside. He said that the helicopter would be arriving in about 15 minutes time. There was clearly a well prepared plan in place to deal with such incidents.
Shortly afterwards the helicopter could be seen and the operation was carried remarkably swiftly.
We were in our cabin at the time and no doubt we will hear from fellow passengers who were closer to the action.
