In Indonesia, it takes a little time to find the right investigators who will produce the correct crash findings, for the right amount of money. One mustn't rush these things. I won't even mention the Will of Allah!
That right there is the root of the problem ... EVERYTHING is for sale in Indo if the price is right : the job, the licence, the skill test, the maintenance release, even the accident investigator findings. Look at the Silkair suicide fiasco or indeed the recent history of Lionair itself with regard to tail strikes and overruns ... and then look at the Indo CAA response ... corruption is like breathing down there, it's just a way of life. Expect absolutely nothing to change in the face of this latest embarrassment.
