The trials of 68 former officials charged with kidnapping, torture and murders at a naval college between 1976-83...have begun.
Many thousands of Argentines were kidnapped, killed or simply disappeared during the 'Dirty War'.
Some were burnt...while others were drugged...and pushed from planes into the Atlantic.
The 68 are charged in 800 cases...and over 900 witnesses are expected to testify.
Observers expect trials to last 2 years.
