I think Sebastian Kawa was referring to the combination of 1000km flights and racing. The African camps (I have not flown in Namibia but have flown from Gariep in South Africa) are very relaxed and laid back. Most gliders are self-launchers or at least fitted with sustainers so long retrieves are not an issue. Everybody assists everybody and pilots set their own tasks according to their mood/attitude/experience for the day. Pilots think nothing of taking days-off and experiencing the wildlife or just relaxing by the pool between flying days. Competitions are a bit different - it's a far more stressful environment. Now combine 1000km tasks into the competitive racing environment - and Sebastian is then correct when he states its a recipe for accidents.
