Inter-service transfers to the AF are currently on hold. But that seems to change on a frequent basis.
A few years ago, Army Blackhawk pilots were being given a commission in the AF if they would come over to fly our Blackhawks.
Call AF Personnel Center at DSN 665-3708/3711, and if you are lucky enough to get them to answer, let them know you are an Army helo pilot looking to transfer to the AF.
