Before I became a pilot, I didn't know who the fark CASA was and nor did I care. Even now, none of my friends or family have any idea who CASA is or what it does.
I doubt the general public has any idea, either.
(In fact, I'd like to see the results of a survey asking one simple question: "Have you ever heard of CASA and do you know what it does?")
But one thing we all knew then and now is that good pilots and engineers make safer skies.
