Just to clarify, I have no idea or opinion on the chances of even getting into any of the flight programs. My above posts is with the assumption that a person has made it to flight training.
I can say for the CG, if you are medically qualified, and a good performer in OCS, you have a strong chance of getting selected, and if you don't initially, you will likely get it eventually if you remain a solid officer and stay medically qualified. The Academy used to not allow grads to go straight to flight school, then did, and now, I don't know. That rule changes with the whims of the current leadership.
