Indonesian officials say a passenger plane en route from Java to north Sulawesi island with 102 people on board has disappeared and they do not know what happened to it.
The officials say rescue teams are searching for the missing Adam Air Boeing 737 jet, which sent out distress signals shortly after midday Monday over central Sulawesi.
They say the plane was in the middle of a two-hour flight at an altitude of about 10-thousand meters when it lost contact with air traffic controllers. It carried only enough fuel to fly for four hours.
A Director General of Air Transport, Ikhsan Tatang said the jet was flying in bad weather but that before leaving, the crew had received weather information for the whole journey.
The plane was carrying six crew members and 96 passengers, including 11 children.
Adam Air is a privately owned, low-cost airline that began operations in Indonesia several years ago. Most of its flights are domestic.
Last year, one of Adam Air's jetliners lost all communication and navigation systems during a flight between the Indonesian capital, Jakarta, and Makassar on Sulawesi Island, forcing the pilot to make an emergency landing.
