Air Force enlisted jobs?

I've been looking into the air force recently and have been interested in quite a few jobs. First I was looking at imagery ysis, where are they usually based and would that lead to a career in the CIA, NSA or FBI? Also what MOS's work in the space program, that would be awesome. Lastly, what job in the air force leads to a great job in the civilian world. Would it be worth it to forget about getting a job for the future and be a loadmaster, and be a cop when i get out which is what i originally planned?
