Tinker is the main base in OK, it might have just been a re-fueling stop or something else at Tulsa (reserve base) coming and going, it's been over 50 years since i mustered out, I imagine there's a lot that has changed, AF-SOC works all over the world, supply's info to the "spooks" for OOC opp's Can't tell ya anymore or they'll be kicking in my door....Check the markings, are they our aircraft or "theirs?"
