Indonesian authorities have intensified search efforts after a surveillance aircraft carrying 11 people went missing in South Sulawesi.
The turboprop aircraft lost radar contact on Saturday afternoon while flying over a mountainous region near Maros. It was nearing Sultan Hasanuddin International Airport when communication suddenly stopped.
The aircraft was operating a fisheries surveillance mission for the Ministry of Marine Affairs and Fisheries. It was not a commercial passenger flight.
Details of the Missing Aircraft
The plane had eight crew members and three government officials onboard. All personnel were engaged in official duties at the time.
Air traffic controllers last instructed the aircraft to correct its landing alignment. Shortly after that communication, the signal disappeared.
Preliminary tracking data suggests a rapid loss of altitude before the aircraft vanished from monitoring systems. However, officials have not confirmed this information.
Debris Sightings Narrow Search Area
The search area has now narrowed to Mount Bulusaraung within a protected national park. Hikers in the region reported scattered debris on the mountainside.
They also described signs of small fires and fragments resembling aircraft material. These reports prompted authorities to redirect aerial and ground teams.
Local rescue officials believe the aircraft may have crashed near the mountainโs peak. Weather conditions have made confirmation difficult.
Challenging Terrain Slows Rescue Efforts
More than 400 personnel are involved in the operation. Teams include military units, aviation experts, and disaster response authorities.
Helicopters, drones, and ground search units are working simultaneously. However, steep terrain and dense forest continue to hinder progress.
Poor weather conditions in the national park have further complicated visibility and access. Despite this, operations remain ongoing without interruption.
Manufacturer and Authorities Respond
The aircraft manufacturer has acknowledged the incident and confirmed technical support for the investigation. Specialists are assisting authorities as needed.
Officials have stated that rescue efforts remain the top priority. Any conclusions about the cause will follow a full assessment.
Broader Safety Concerns
Indonesia has faced several transportation incidents in recent years. Many challenges relate to geography and weather conditions.
Authorities continue to stress improvements in monitoring and safety enforcement across remote regions. The search will continue until the aircraft and all occupants are accounted for.
