I found that Aerospace as an undergrad is too specialized. I would recommend a Mech degree and specialize at the masters level. I have worked in the space industry and now am in the defense industry. It won't matter what industry you're in for the first bunch of years while you get general experience. When you're performing "enginerring" you can easily lose sight of the end product. Just focus on getting the fundamentals down like vibration, heat transfer, thermodynamics, fluid mechanics, mechanism dynamics. Then you will be in a better position to decide what type of position you want regardless of industry.
