I was watching the T-birds form up for their demonstration at the Air Force Academy graduation ceremony. All 6 were tooling around for a bit, then formed up with a KC
-135R and took on gas before they left for the show. I was observing at a turn point that was basically one mountain ridge behind the academy (at work..). Is this common for a display team to do, or was this just because of the low internal fuel capacity of the F-16?
