Seems like the Air Force is trapped in a vicious underhiring/overhiring cycle. When I was in college I did Air Force ROTC. A lot of my peers had pilot slots; I was poised as a 17D (Cyber Ops). After graduating, my training date was put on hold virtually indefinitely. Eventually I got an email that the Air Force had commissioned way too many officers and were looking for people to voluntarily leave with no commitment/…
And...there is the other end. My brother is a pilot and was retired by the Air Force because he had been in so long...so out he goes. Now he is a contractor flying drones for them getting paid 3x as much while drawing a hefty retirement. My brother loved the Air Force and wanted to stay...now he gets to stay and get paid a boat load more. Air Force brass not very smart.
Contracting him could easily still be cheaper than having him still be in.
