JAKARTA, Jan. 4 (Xinhua) -- The United States and Singapore have assisted Indonesia in searching a passenger plane which went missing on Monday with 102 people aboard, Indonesian Transport Minister Hatta Rajasa said here Thursday.

    The Singaporean government has sent an aircraft equipped with sophisticated technology for searching and the U.S. government, whose three citizens were on board the ill-fated plane, has helped search with remote sensing by satellite, said Rajasa.

    The searching of the Boeing 737-400 commercial plane operated by Indonesia's Adam Air Corp., has conducted through air, land and sea waters and involved Indonesian air force, navy, police and rescue team since it went missing on Monday.

    "We deploy four aircrafts today. Navy ship with surveillance equipment today begun to move to the waters of Makassar," he said.

    "The Baruna Jaya ship that has capacity to detect up to more than 1,000 meters below the sea surface is deployed today," said Hatta.
