Here is some more precision wingsuit flying by from all over the world (South Africa, China and Norway) in 2011. The scenery is only outdone in this video by the athletes buzzing roads, trees, cliffs, gondolas, and anything else you might find on a mountainside. Other than that, I really have no further explanations for wingsuit videos, because A: they are fairly self explanatory, and B: I guess the word ‘extreme’ pretty accurately sums up the whole sport.
To add to this commentary however, I did come across ‘The Corliss Resolution’ as a theory to explain wingsuit proximity flying, and why it is increasing in popularity, as well as why extra-terrestrial life has not been discovered. Simply put,
“It takes longer to develop space colonization than it does to invent an activity more fun than survival”
