Federico Ibanez clings to a fence crowded with blue-and-white Argentine flags, rosary beads and messages of support for his brother and 43 other crew members of a missing submarine that should have arrived to a naval base days ago. But his hopes are slowly dwindling.
Ibanez and other relatives of the sub’s crew are now growing increasingly distressed as experts said that the vessel lost in the South Atlantic for seven days might be reaching a critical period of low oxygen on Wednesday.
The ARA San Juan went missing on November 15 when it was sailing from the extreme southern port of Ushuaia to the city of Mar del Plata, about 250 miles (400 kilometres) southeast of Buenos Aires. The Argentine navy and outside experts worry that oxygen for the crew would only last seven to 10 days if the sub is intact but submerged. Authorities still do not know if the sub rose to the surface to replenish its oxygen supply and charge batteries.
The German-built diesel-electric TR-1700 class submarine was set to arrive on Monday to a naval base in Mar del Plata, where local residents have arrived bearing messages of support for relatives of the crew anxiously waiting for news.
More than a dozen international air planes and ships have joined the maritime search despite stormy weather that has caused powerful waves of more than 20 feet (6 metres). The search teams are combing the waters in a wide area of some 185,000 square miles (480,000 square kilometres), which is roughly the size of Spain.
From the shore, Jorge Villarreal, kept his eyes transfixed on the ocean, hoping to catch a glimpse of the vessel that carries his son, Fernando Villareal, a submarine officer.
