Not participating as a pilot, but having been to B.A. and Santiago. I have always dreamed of seeing the lands south of these cities. I flew over the Andes from B.A. to Santiago countless times, but every time I whole heartedly admired the majesty of that mountain range respecting the harshness of the environment below.
The only trip I flew just a few times that compared was from Manaus to Lima, over Lapaz, Lake Titicaca and the arid Andes between, I remember looking down at the mountains and seeing roads cut into them.. I could not imagine transversing this terrain.
