One of the most chilling pieces of evidence of the brutal Argentinian dictatorship, which lasted from 1976 to 1983, is a small airplane. The Skyvan, a British-made aircraft, was used by Argentina's military junta to make political opponents disappear. The "death flights" saw dozens of people killed when they were thrown from the planes into the sea. The location of the last Argentinian Skyvan was a mystery for decades. But it was recently found in Florida and returned to Buenos Aires: a powerful symbol for families of victims of the regime, as well as for survivors.
