A U.S. Navy ship would try to determine if metal objects found off Sulawesi Island were the wreckage of a Boeing 737 that disappeared a week ago carrying 102 people, AP quoted officials as saying today. «We can't tell what it is,» Eddy Suyanto, the head of search and rescue operations, said of the debris found recently by an Indonesian naval vessel in three locations at depths of up to 1,500 meters (yards). The USNS Mary Sears, which has sonar and satellite imagery capabilities, has been called in to see if the metal is part of Adam Air Flight KI-574, which fell off radars in the area after battling 130 kph (80 mph) winds. It was expected to arrive late Tuesday and to be put into action early Wednesday, said U.S. Embassy spokesman Max Kwak.
