 Documentary on the air collision between a UPS Boeing 757 freight plane and a Russian Tupolev 154 carrying 69 passengers, the majority of who were Russian minors en route to a holiday in Spain, in July 2002. The collision happened at an altitude of 11 kilometers above Überlingen near the Bodensee between Switzerland and Germany. The documentary details the subsequent investigation on the air traffic controller who was initially blamed for the accident (and who was murdered by a grieving Russian father) and the company he worked for in Zurich - Skyguide.
