Tampomas II sinking (1981)
The passenger ferry Tampomas II caught fire and sank in the Java Sea, killing nearly 600 people by some estimates. The ship burned for days while rescue attempts were hindered by the same rough conditions now slowing this rescue.
Hundreds of bodies were never recovered from the Java Sea.
The disaster became a reference point for Indonesia's recurring ferry safety failures, though enforcement remained lax.
It happened in the same body of water, in similar weather, and is the standard Indonesian officials cite for the region's worst maritime losses.
