well...
well, aeronautical engineering has absolutely no relevance to becoming a pilot. the aerodynamics is far more advanced than a pilot needs to know, and im sure a pilot doesnt want to know the copmosite layup of various components of his aircraft.
dont do aero eng. unless you want to work in the design/manufacture side of the aerospace industry...otherwise you will end up being an overqualified pilot! well, maybe not overqualified as im sure it all helps, but choose an easier degree, one which causes less stress and hair loss!
