JAKARTA, Jan 26 (Reuters) - Retrieving the flight recorder of an Indonesian plane that vanished on New Year's Day from sea water at least 1,000 metres (3,300 ft) deep will be difficult and costly, officials said on Friday.
A U.S. navy ship with specialised equipment that has been helping search for the missing Adam Air Boeing 737-400 detected signals suspected of being from the plane's flight recorder, the U.S. embassy in Jakarta said on Thursday.
Wreckage from the missing started turning up in waters on the west coast of Sulawesi over recent weeks, but crash investigators want to find the black box and main body of the plane to determine the fate of the doomed plane.
There were 102 people aboard the missing plane including three Americans, a father with his two daughters. No bodies have yet been found.
