I watched the 20 minute video. It was very well presented. The most important issue they raised was that 1-2-Go gave flight time figures for the pilot/copilot that were monthly totals and were lies. The actual figures for the month from the daily figures showed they were over the top by 30 hours. (Excuse me if I am not using the correct terminology).
So 1-2-Go lied to the investigators.
One lie here, one lie there, why should we believe anything 1-2-Go or Udom says?
