Is it possible to own my own company while in the Air Force?

When I graduate from college(currently a freshman w/ major in Manufacturing Engineering), I would like to join the Air Force, but at the same time I want to be an Entrepreneur and start my own Aerospace company. I know being in the Air Force will build my character and give me leadership experience, but at the same time I want to do my own thing as well. So long story short, is it possible to own my own company while in the Air Force?
