You said military is your last option. How close to 29 are you? Just realize that you need to start pilot training by 30 (USAF) sometimes waiverable. You actually are guaranteed a pilot slot through OTS If they hire you for that and you pass your physical. If they offer you something else you can decline. This assumes you have a four year degree. I'd consider the reserves or guard, you can keep your fire fighting job and fly on the side (eventually).
