After hundreds of years of isolation being served only by the regular mail boat from Cape Town every few weeks, St Helena will have an airport (£250m) opening next year. The population is only 4000, wages are low and the opening of the air link is likely to change this small territory for ever. It was once the home of Napoleon after his defeat at Waterloo. Otherwise it has no real claim to fame. It is located in the South Atlantic.
Tristan da Cuhna much further south remains without air transport.
Relatively near Ascension Island has air links with the UK and the Falkland Islands.
