Soviet sub caused tub of trouble A Soviet submarine that sank off the Danish coast while on its way to a Portugese scrapyard reposes rather gracelessly on a pier in Copenhagen Friday after it was lifted off the ocean bottom by a Soviet seagoing crane. Danish officials will be forced to leave the whiskey-class vessel where it is until they can obtain a crane capable of lifting the beastly thing, which weighs more than 1,000 tons. It should come as no surprise, perhaps, that it was unable to float!
