Argentina's search for missing sub hampered by bad weather

Argentina's military pushed forward Saturday with the hunt for a submarine that has been missing with 44 crew aboard for days, but said that bad weather has hampered the search.There has been no contact with the ARA San Juan since early Wednesday, according to the navy, prompting Buenos Aires to launch an air and sea search for the missing vessel.Nearly 80 percent of the search area has been scoured by ships and aircraft so far, Argentine navy spokesman Enrique Balbi told a news conference.
