Interesting website, and good luck to the guy. As he says, most people do this sort of thing with loads of back-up; it's great to hear about someone who just gets out there on his own, and flies...and flies..and flies.
I met a few Slovenian glider pilots at the recent FEWP (Federation of European Women Pilots) conference in Salzburg; they were really quite amazing...fly way up in the Alps in conditions and terrain that many of us wouldn't even think about attempting. Sounds like he's another of the same breed.
