The last few days have left us shaken and devastated. It is with great dismay that we have received the sad certainty that our founder Rainer Schaller and his son have been identified as the deceased of the plane crash in Costa Rica. His life partner, her daughter, our colleague and the pilot, who were also on board, are still among the missing. At this difficult time, all of our sympathies go out to the families of all those who lost their lives in this accident or remain missing.
