I enlisted in the Air National Guard and got most of my college paid for by the GI Bill. In my free time I worked at an airport and used the money for flight training. At age 25 I applied and got accepted for Active Duty pilot training. You can also apply to Air National Guard/Air Force Reserve units to have them send you to AF pilot training. You have to start pilot training (at least in the AF) by age 30, so you have plenty of time. The civilian route is certainly feasible, but is a longer, more expensive road. Either way, work hard, fly as much as you can in whatever you can and do good in school. Intelligence and work ethic and a little luck will take you far in this career. Best of luck!
