10 years after the AF implements universal assignability due to use of a common training platform and program, crossflowing between MDSs won't be a big deal...especially for promotions, staff tours, etc
I see it like this: the AF wants you to be a combat-ready pilot for about 5 years, after 4 years of tng (regardless of MDS).
Of the next 11 years, It wants you to spend 2 in school, and 10 on staff/ALFA and in the schoolhouse, then retire you as a Maj or Lt Col at 20-22 yrs. if they can get 100 to do that, about 20 of those 100 will also get command tours and/or early promotions.
Point being: the AF believes there will ALWAYS be just enough "old heads" around in every MDS to take the young uns to war...and your proficiency/capability in the jet is assumed A-OK--which is why your OPR must be filled with non-flying achievement.
The AF doesn't have a problem filling cockpits, it has a problem filling the insatiable staffs and exec billets and CAGs with pilots. So, let's go back to a standard program for all, 60-70 student class sizes, a 40% washout rate, and budget for the increased flying hours and maintenance, plump up the transition courses, and man every squadron and staff to 95%.
Oh yeah, at the same time, reduce pilot initial ADSC back to six years, and eliminate the bonus and advanced flight training ADSCs.
