Flying anywhere in PNG is challenging and very often scary. I worked fly in-fly/out in PNG for a few years, working at Ok-Tedi gold and copper mine up in the Star Mountains. Flying into Tabubil or Kiunga in bad weather was, interesting to say the least , threading the. way through the mountain valleys with cloud above and sometimes below, in a Beechcraft King Air. Also flew into Port Moresby a few times from Cairns.
