Just wanted to add that the sims version of … Saint Helena … is still, well, not good.
The airport (FHSH) is still not part of the official sim list of airports. This means you can not click it in the map as a point of departure.
OpenStreetMap has the runway and related roads and buildings in its dataset, so it is somewhat strange to me, that MSFS did (still) not produce a matching representation inside the sim world.
