Quite sad, my dad introduced me to the guy, he was a pilot from Australia who has lived in Indonesia for a couple years, and went back to Australia for a holiday with his Indonesian girlfriend Endah, that's all i know from my personal experience with him, but he was a really lovely guy, I've met his girlfriend (Endah) but we were never close, http://www.abc.net.au/news/2017-01-26/two-dead-in-australia-day-light-plane-crash-in-perth/8215720
