On April 10, 2010, a Polish Air Force Tu-154 goes down near Smolensk, Russia, killing everyone aboard, including President Lech Kaczynski and dozens of senior officials on their way to a memorial for the Katyn massacre. This Dutch television documentary, produced by Amsterdam's Rerun Productions, follows the investigation that came after, an inquiry that quickly became as contested as the crash itself. Aviation experts walk through the technical findings on weather, pilot pressure, and airport conditions, while journalists and politicians lay out the competing narratives that took hold in Poland almost immediately, from official negligence to darker theories of foul play. Archival footage and photographs place the crash in the context of Polish-Russian relations and the Katyn history the flight was meant to commemorate. The film tracks how the disaster split Polish politics for years afterward, with rival camps disputing the black box data, the wreckage's location in Russian custody, and the official conclusions themselves. It treats the crash as a case study in how an air disaster becomes a political battlefield.
