We left Rio in the CV990 and flew across open ocean for hours until our dusk landing at the new-and-improved St. Helena island airport. (arguably the most remote airport in the world)
The next morning we "hoisted sails" and set off for another few hours across open ocean to Cape Town, South Africa.
