I wonder why there´s none in South America. Sweden?! It would be a very unlikely place for a landing (except, I think in high inclination military missions). There´s a clustering in the Indian Ocean with several options, but you have a void between Polynesia (!) and South Africa in the southern hemisphere. Go figure... A propos, we have a 5 km runway very near to my place, with all conveniences of civilization, case one of those NASA lurkers are reading this.
