There are a few that I know. Plenty of frogs get pilot licenses, but their military skills are so marketable right now that flying doesn't make economic sense for most.

If you REALLY want to do this...from you position (age, prior mil, no degree) I would STRONGLY recommend that you enlist in the navy direct-entry SEAL program. Get in shape first, then do it immediately.

- You're getting old...you're not too old, but you will need as much physical resilience as you can bring.

- Officer slots out of any source (ROTC, USNA, OCS) are extremely competetive. Also you're held to a somewhat higher standard in BUDS.

- Once you are on the teams, you can basically go get a degree at your convenience and then they will happily commission you if you want. This way you can have as many platoon tours as you can stand, and then upgrade to officer...after which you'll get maybe two more platoons and then it's off to desk jobs.
