Next question, do you (AF) often get commanders who are not creditable in the aircraft? If this is truly your issue that your SR LTC's and COL's cannot even fly their aircraft as descent pilot, I see your point. But your argument is more from the stand point of schools and masters degrees really do not expand you educational views. If what you are saying is you would be better off staying in the line you entire career, I think (my opinion) your service will end up with great LTC's. But you will suffer in the long run. The services are run by the O6's. I can tell you from the Army stand point on education, your service will lose out if you get rid of your higher educational opportunities. I do realize that the Army view on leadership is much different from the AF view. But you want to have O6's who can compete with the other service O6's. As the career manager for some of the Army types, I was able to talk to them about the SSC's. I never spoke to one who said it was a wasted experience. They all told me it was one of the best educational schools they ever attended. From the stand point of being able to read everyones evaluations (and even work for some of them), they became some of the best commanders we have had. Not saying all, but the knowledge they gained from the SSC's combined with a key DC position, gave them some skills beyond the average commander.
PS I was not alluding to anything, just asking to understand your thoughts.
