Argentina brings back 'death flight' plane for historical accountability.

A plane used by Argentina's military dictatorship to throw political detainees to their deaths from the sky has been returned to Buenos Aires and will be added to the Museum of Memory. The plane was discovered in the US and is the first ever proven in court to have been used in the "death flights". The junta is widely considered the most deadly of the military dictatorships that ruled much of Latin America in the 1970s and 1980s. Human rights groups estimate 30,000 were slain, many of whom disappeared without a trace.
