Okay, no more 5-20 year old info...here is the 100% CURRENT situation.
There is no normal crossflow between tanker, bomber, fighter - at all - in any direction! Period Dot. This does not account for the 1 in a million, 3-star's aid, or reserve/guard exception or some green-door afpc mistake.
All B-52 & B-1 pilots TODAY come from the T-38 track. Reason? They tried the T-1 track back in 98-99 and DID NOT LIKE THE PRODUCT. Period dot. Agree or disagree, that's the reason. Realisticly it's used as a AFPC cushion for fighter slots. It allows JSUPT to have a better chance of getting top guys into fighter slots...but even that is old news - try getting an ACTUAL fighter slot out of JSUPT today (I'm a T6 IP)
B-2's ? This current years message says ONLY Fighter/Bomber or Fighter/Bomber FAIPS are eligible. It's been that way for 2 or 3 years now. Don't waste your time, we've had tanker FAIPS in my squadron get reminded by the AETC/CC to STOP applying. Read the message and you'll actually see a new section that tells you that the Fighter/Bomber issue is NON-WAIVERABLE.
Please don't tell us about how you did it 5 years ago, or how your buddy did it 10 years ago, or some other fictional crap. Might as well talked about sitting nuc-alert in the buff 7 days a week....it's all ancient history.
