Just make sure you know the age limits for pilot training. We had some older guard guys in my UPT class years ago so I know there are exceptions to the norm--know the rules and realize that waiver approval ebbs and flows based on necessity. Also consider that the environment will probably change the next few years with budget cuts and airline hiring. Impossible to predict but I know our local heavy reserve units are very concerned about manning. They are having a harder time keeping full time positions filled by quality folks as their pool of seasoned pilots/furloughees go back and/or retire. Throughout my military career I spent about $300 for testing/prep materials and got an ATP, CFII, and 2 type ratings. But I also had to spend 20 years doing what uncle sam told me to do so the desire to serve is a large part of it too.
