Barry Woods was on LWOP from Canadian Airlines. Only after IFALPA basically told the Korean authorities that they would likely see very little international traffic in their skies did they let Barry head back to Canada on the promise that he'd return for trial. As you may have guessed, he did not.
This is the story I got from a friend who's ex Canadian, quite anumber of years ago, so I may be a tad off, but that's the jist.
