The most tragic disaster in the Tatra mountains occurred in January 2003. A group of high school students from Tychy heading towards Rysy mountain were caught in an avalanche, resulting in 8 fatalities. During the second day of the rescue mission, a critical error occurred in one of the helicopters, Sokół, halting the functions of both of the engines. The pilot, Henryk Serda, was able to perform autorotation landing, causing major damage to the vehicle but avoiding harm to any terrestrial objects. Shortly after the incident the pilot was fired for breaking the aviation safety laws. Henryk re-appealed and was found innocent due to discrepancies in the officials' reports. A vehicle inspection, confirmed by the manufacturer, raised the possibility Sokół may have not been maintained properly. This tragedy was adapted into a movie, Cisza (The Silence), premiered in 2010.
