>> Hope is fading among relatives of the 44 crew members aboard a missing Argentine submarine. After days of waiting for news at the Mar del Plata naval base loved ones have gone home. But the Argentine Navy vowed to keep searching for the ARA San Juan that went missing nine days earlier with only one week's supply of oxygen on board.
The Navy on Thursday said a sound consistent with an explosion was detected in the South Atlantic Ocean around the same time the vessel sent its last signal on November 15th. But Reuter's correspondent Luke Cohan says there are still many unanswered questions.>> It's still not known whether the submarine was attacked, or if the sound that appears to be an explosion even sunk the submarine.
There's still a lot of concern about the fate of the 44 crew members aboard.>> Many family members are accusing the Navy of sending their loved ones out in the vessel that they say was over 30 years old and most likely not properly maintained. The submarine was on route to Mar del Plata when it reported an electrical malfunction shortly before disappearing, prompting a massive search effort by many nations in a race against the clock.
