I'll admit I know nothing about this so this is purely hypothetical (AKA BS) but..
could it be due to the fact that historically many military pilots transitioned to commercial/airline jobs after they were done with their service, but now that commercial pilot pay is low, there are just better career tracks that are more practical? Especially now that the possibility of their military careers will be cut short by drones in the long run?
Ah, no! "commercial pilot pay is so low". Where did you come up with the? Obviously not from any sort of factual source.
The drones don't have anything to do with cutting anyone's military service short. The overall size of the force is being reduced by geniuses on the east coast who don't have a grip on reality and the world around them. If a particular individual has been in for some length of time and the "geniuses" start cutting back force size, there is incentive to "cut their military career short" either voluntarily or involuntarily. The Predator drones have nothing to do with it. The "drones" on the east coast do.
Bottom line here is, if you have not spent a considerable time in voluntary service a sacrifice to you country, you don't appreciate the true facts.. If you are basing your "facts" on what you see on TV, read in the papers, or, the oh so accurate Internet blogs, you have been duped with the information "they" want you to think you know as facts.
