Authorities in Indonesia lost communication with a small Rimbun Air cargo jet 50 minutes after it took off in the country's easternmost province of Papua on Wednesday.
The jet is being sought by local airport authorities and the National Search and Rescue Agency.
The Twin Otter 300 plane was carrying building materials from Nabre district to Intan Jaya district.
A pilot, co-pilot, and technician are on board, according to the Transportation Ministry.
“Until now, no communication has been established with the Rimbun Air PK-OTW plane,” stated Adita Irawati, a ministry official.
In recent years, Indonesia, a vast archipelago nation with a population of almost 270 million, has been afflicted by transportation mishaps, including plane disasters and ferry sinkings.
