An “operation error” related to a ventilation valve, called 'Eco-19,' could explain the mystery of the tragedy that befell the ARA San Juan, the Argentine submarine that disappeared almost a year ago with 44-crew members on board. The new details emerged in a report currently being prepared by a commission of experts based inside the Argentine Defense Ministry.
Water entered the snorkel of the Argentine submarine ARA San Juan, causing its battery to short-circuit before it went missing November 15, a navy spokesman said on Monday as hope dwindled among some families of the 44-member crew.
