Namib Desert, Namibia
Definitely a cool jump is from the Namib Desert, even if you are in Namibia or you jump somewhere near the Atlantic coast of the desert.
Basically, your jump starts at 10,000 feet and before you land the experience is unique giving you the feeling you come from another world and populate for the first time this vast and lifeless place.
The 5 minutes you make from your ultimate altitude and until you land is unique also in the fact that the powerful wind creates, from the sand in the desert, figures and patterns unseen before.
So think about it, who wants to experience the apocalyptic emptiness of this vast desert combined with the rush of a skydive with only one string being capable of saving your life before hitting the sand.
