CES Stands for....
Of course it's not flying, but CE is hurting for officers. If you have a civil, electrical, (an EET would also work), architectural, mechanical, and a few other flavors, you can come to work without any Air Force training. You have the degree and that's all you need to start. There is Silver Flag which you have to do every two years I think, and some other stuff. My unit has a great bunch of people which is why I'm there vs. flying. It would get your foot back in the door and you might like it. Between my unit and one in a neighboring state, there are 5 openings for CE officers. Lots of enlisted openings too that require schools if you know someone interested in learning that end of the business.
