We're back to the annual T-1/T-38 dick measuring.
Having flown both aircraft there's no argument that the T-38 requires more stick and rudder skills, but that wasn't the point of the T-1.
FWIW, this disagreement will be moot in the next decade though because there will be another T-X buy to replace the T-1 and we're going back to Generalized UPT (GUPT). That's the official name. After T-6s some guys will go to Rucker but after that there will be an advanced phase track select.
