I too am of a Mexican background and wondered the same thing. I actually read an article, and I am sorry to say I can't remember where, that talked about U.S. airline hiring practices and ethnicity. Basically, the article said that airline pilots as a whole represent the general population other than women. Basically, around 75% of pilots are White, while Blacks and Hispanics each represent around 10% of the airline pilots. The other 5% being other. Those numbers pretty much represent the ethnic make up of the country.
