From military officer to banking, possible?

I really want to get into private equity after college but first and foremost my life dream is to serve as an Air Force officer (wanted to do this since i was 6).

I've been doing a lot of research on people who have done this, at least into ibanking, but there doesn't seem to be a cut clear way of doing this.

Unlike the profiles i've read, i don't go to a Big Ten school for my undergrad, but I am an engineering major currently with a 3.3 gpa doing AFROTC.

I was thinking about applying to be either a civil/developmental engineer or intelligence officer when it comes time to commission, but would love to fly

From there do my best to get into a top MBA program (pref. Harvard, Stanford, UPenn, Booth)

Then what?

By the time this is all done, i'd be 30yr old, is that to old to break into banking?
