A DHC-4 Turbo Caribou PK-SWW left the town of Timika last night with 4 persons on board, but lost contact less than half an hour later. Local media report that an ELT signal was received; However, thick fog is preventing SAR teams from confirming the crash location. The Caribou is owned by a local authority but operated by a third party company. It's unclear who the operator is (either Trigana or Alfa Trans).
