And then we had a visit from a EC 155. A doctor was flown in. We heard, the watertreatment of the Rappensee Hütte was faulty and several guests got quite sick by drinking the water. That explained the many helicopter landings at the Rappensee Hütte. It was quite interesting to watch, since the official landing place was the patio. So the helicopter had to hover over the ground, and the doctor had to jump out of the aircraft.
