On July 17, 2014, Malaysia Airlines Flight 17 was flying from Amsterdam to Kuala Lumpur when it was struck by a missile over Hrabove, a town in Ukraine's Donetsk region where Russian-backed separatists were fighting the Ukrainian army. This episode of the What Went Wrong series reconstructs the flight's final minutes and the wreckage field scattered across farmland, using radar data, satellite imagery, and interviews with air crash investigators to trace the weapon's trajectory back to its launch site. It weighs the competing claims that emerged within hours, Ukrainian government accusations against the rebels, Russian counter-claims about a fighter jet, and the physical evidence recovered from the crash site that eventually pointed investigators toward a specific missile system and launch crew. The film also notes the 2025 finding by the UN's aviation tribunal in The Hague holding Russia responsible. It is a case study in how forensic aviation investigation works under wartime conditions, and in how long it can take politics and evidence to arrive at the same conclusion.
