Luke Skytoddler is spot on.
Indonesian aviation is in league of its own. Most Indonesian captains don't speak good English, have no real concept of CRM and don't follow SOP's. Its no joke, there is a reason why their safety record is what it is.
I recently witnessed a Batavia 737 land in a thunderstorm with a 10kt tailwind on a 1800m runway, only touching down around half way. I started to get my camera out as I thought I was witnessing a YouTube moment. They managed to stop 2 meters from the end, using full reverse all the way (even below 40kts). Pretty much sums it up I think.
If you still feel like its something for you, then by all means go ahead and sell your soul to Merpati. Just remember you were warned!
