THREE years after the Lauda Air crash in Thailand claimed the lives of 223 people - 52 of them from Hong Kong - the cause of the accident remains unknown.

  Flight NG004, which originated in Hong Kong, crashed shortly after takeoff from Bangkok three years ago today. It has never been established why the left-hand engine of the twin-engined Boeing 767-300ER went into reverse thrust.
