Heard from ex KAL boys, now in the sandpit, that there was a young Japanese chap who claimed to be ex Airbus factory pilot who conned KAL and became a B777 captain for a couple of years before he was outed by some Taiwanese chaps who pointed out to the koreans that he was only an F/O in Taiwan, never a captain before he went to KAL. He then did a runner!
There were also stories of South African cruise captains who duped KAL to become full fledged captains on the 744. However because senior KAL management was involved they had to let their appointments stand for fear of massive " loss of face " not forgetting the public outcry were they to fess up. Also a few aussie f/os from the '89 disputes went to the backwaters of Africa and the Middle - East for a couple of years and turned up as wide bodied airbus and B747 classic captains in KAL. Again they were protected by expat management pilots in KAL, and for fear of complications the KAL management just did nothing even though the KAL pilot union reported it.
I think as the Korean pilots venture out there will be more revelations.
