Visiting in Denmark a while ago, I wrangled a day at a nearby soaring club, in a high performance tandem. Great group of pilots. Different experience than the US. My first winch launch for one, powered by - of all things - a humongous American V8. Great day, good cloud streets. Long day… Had to pee and we were still an hour+ away from home base. Fortunately I had along a wide mouth 1L water bottle which I’d gradually emptied during the day. A bit awkward but it worked. Only slightly embarrassing.
