I know of only one, but early on (when it was still called a UAV), Eagle-Pred-Eagle... he has since gone back to AETC, and is now finishing up a 365 no-fly in Qatar with an AETC fly follow-on, which will put him current at 20+. Good deal for him. According to the guys at the porch on my last visit (a couple months ago), expect RPA now to be a one-way door. That said, 19 AF/CC renewed the rumor a couple weeks ago that UPT to RPA guys might see a cockpit some day. I wouldn't bank on it, though.
