Malaysian Airlines lost 2 large aircraft within the past year or so and now a large plane from Indonesia is lost and my guess, crashed somewhere in the ocean.
Hopefully, they will be able to find this plane and perhaps some survivors.
Update: They still have not found the plane even though Indonesia and Singapore have been searching for hours for the plane.
