A former New Zealand pilot says flying for an Indonesian airline can be dangerous, and those who do so are warned to take precautions in Papua.
This comes it was reported on Tuesday night that a New Zealander, working as a pilot for Susi Air, was taken hostage by separatist fighters in West Papua.
Reuters reported the West Papua National Liberation Army claimed responsibility for the attack, saying the pilot would not be released until the Indonesian government acknowledged the independence of West Papua.
The pilot was identified by Reuters as Captain Philip Merthens.
It is still unclear what happened to the five passengers reportedly on board, but the plane is said to have been set alight by the separatists.
Prime Minister Chris Hipkins told RNZ on Wednesday New Zealand officials in Indonesia were working on the case.
He said while standard practice was to give hostage situations minimal airtime, he could confirm the New Zealand Embassy was aware of the situation, and he would be receiving a full briefing.
The Ministry of Foreign Affairs and Trade said the New Zealand Embassy was providing consular support to the family, but for privacy reasons it would not be commenting further.
A former New Zealand pilot, who flew for Susi Air for just over a year ending in 2017, said pilots were warned by the airline to take precautions in Papua - things such as keeping a low profile, travelling in groups, finding a driver to take them around, and not leaving the compound at night.
Susi Air was known for flying government-commissioned "perintis flights" - pioneer flights - carrying mostly freight to remote areas of Indonesia, he said.
These were subsidised by the Indonesian government, intended to open up regional development.
Susi Air was founded by a former Indonesian fisheries minister, Susi Pudjiastuti.
The pilot who spoke to RNZ said the airline still ran the largest fleet of passenger-carrying Cessna Caravans in the world, and flew all around the Indonesian islands, including to Papua.
Susi Air flights carried mostly freight, flying from tiny regional towns into main centres, picking up coffee beans, sugar, rice, and bringing in daily goods like washing powder
According to online reports, including aviation-safety.net, the plane flown by Captain Merthens was a Pilatus Porter, which only requires one pilot - unlike the Cessna Caravans, which the pilot said was required to be flown by two people at Susi Air.
The pilot said it was relatively common for foreign pilots to work for Susi Air. Those wanting to get more hours under their belt to be considered for a commercial airline back home would go to Indonesia to do so.
The situation within the country was tense, but most pilots saw it as part of the job.
"Most are just there to get their hours up and get out," he said.
Since the region was brought under Indonesian control in 1969, there has been a low-level battle for independence with the conflict escalating further from 2018.
"The smaller islands are being forced to align with a culture established in Jakarta," he said, and the Indonesian military had been "needlessly cruel and violent" in its oppression of the West Papuans.
As a white foreigner working for the Indonesian state, it was conceivable that Captain Merthens was in real danger - foreigners were, with some frequency, seen as pawns in this way, he said.
He said it was almost certain that the Indonesian government would not give in to the demands of the separatists.
He had also heard reports of an aircraft being shot at while departing Papua, with bullets found lodged in the airframe under the pilot's seat.
