Just before I joined KAL in 2000, there was a French guy who claimed to be a B777 skipper from Lauda Air. His course mates had misgivings but did not raise the matter as they probably wanted to see how far he could go with the bluff. He made it to the final stages of OE training, but the white knuckles and trouble with decision making showed him up. Unfortunately there were a few bona fide T7 drivers from Lauda who enlightened KAL flight admin. The strange thing was that he had all the correct documentation, recommendations etc from France and Austria enough to fool the Koreans for quite awhile!
Certainly heard of the successful stunt pulled by the South Africans. It seemed only the Canucks bitched about it as they lost the chance of upgrade from the A300-600 to the B744; they finally settled on the T7. Strange that they made no formal complaint to the KMOCT of Korea...maybe they know it would all come to nought as the KAL flight Admin and KMOCT would close rank, cover up all to save face from their massive boo boo!
