I would think that a Masters degree would be a worthwhile investment. Hopefully this never happens, but if you have a heart attack or something else unfavorable crosses your path you have another avenue to go to in aviation. With a masters in aviation management and etc. you could go management, become a teacher at a university or flight school, and probably much more. I like Embry because their online programs do not require you to go into a classroom and you can knock out some homework on overnights.
