My info is dated. And I can't remember if it's Whiting or Pensacola that does UPT (vs UNT) but I've known many folks who've gone through there. Just primary, after track select you go to....actually I think they all go to Vance for Phase 3 (T1s or T38s) but can't swear. Obviously T44s are at Corpus and Helos at Rucker.
Haven't heard anything about it shutting down for AF so yeah, I'd suppose it's a possibility.
