75% is a bit on the high side don't you think? Even if you include the number of captains who were Malaysians went they joined but decided to be Singaporeans.
Anyway, I think what thornycactus meant from his statement is that priority is given to Malaysians for the position of cadet pilot. I can't think of anything other than the age limit. So, partly true I guess.
And I would like to say that I have seen quite a number of Singapore ace pilots in my years, not just Malaysian pilots.
Bagi chance lah bang...
