Man Somehow Climbs Onto Airplane Wing

I have seen some crazy things in my life but I don't think I've ever seen anyone manage to climb around on the wing of a commercial airplane before. How did this guy even get up there? Isn't there supposed to be security for this sort of thing. All I know for sure is that splat that he took on the ground at the end of this video did not look comfortable at all.
