The unique Royal Mail Ship, RMS St Helena, will depart on a final voyage (268) from the remote South Atlantic island of St. Helena on Saturday, 10 February, having dutifully served for the past 27 years. The island, a UK Overseas Territory located 1200 miles off the west coast of Africa could only be reached by the ocean-going passenger-cargo ship service, until commercial flights began operating last October, following completion of an airport.
