OK well you can have your "facts" and I'll have mine. You haven't offered any evidence to support your 'facts", so let's call then what they really are - supposition. How do you know that these pilots didn't have relatives in the US who enabled them to get citizenship? That is certainly highly likely amongst Scandinavians.
I'm not being disadvantaged - you wouldn't catch me flying for Cityjet - but I have a good friend who has been told that he is only going to get a job once all the Americans have been employed. A deal has clearly been done.
