Many years ago a former Boeing instructor pilot joined our South Pacific airline. His job at Boeing in Seattle was to check airline pilots in the Boeing 737 simulator. He told us about a South American country that needed an airline inspector and had interviewed one man who held the rank of "Captain" He was sent to Boeing in Seattle to get qualified on the Boeing 737 prior to taking up his duties as an airline inspector.
He had great difficulty learning how to fly the Boeing 737 simulator - so much so, that he failed the course and was sent back home to his South American country. It was only then it was realised that in his application for the job he had claimed to be a "captain" when in fact he omitted to say he was a captain on a ferry boat. As he was a genial fellow all was forgiven and he eventually became an airline inspector after he was taught how to fly.
