SilkAir has been conclusively proven by NTSB which to me is the final authority on the subject, whether somebody on this forum still considers it an open case doesn't bother me a bit, let them dream of conspiracies and nasty corporations. By the way, there are no 'proofs' in the so called 'court of law', just verdicts which are even further subject to overturns, etc, when you have jurors facing technical data in aircraft accidents all kinds of weird things can happen - like with the Cirrus aircraft crash in Minnesota.
