It had left Jayapura about half an hour before it disappeared, it added.Transport ministry spokesperson JA Barata confirmed the plane had lost contact and said it was supposed to arrive at Oksibil airport just after 15:00."We are not sure what happened to the plane yet and we are coordinating with local authorities," he said."The weather is currently very bad there; it's very dark and cloudy. It's not conducive for a search. The area is mountainous."Trigana Air is an Indonesian airline.Indonesia has a patchy aviation safety record.
