T38 bags an F22
I don't see why it shouldn't be true.
T-38's ,in this role, are usually flown by experienced instructors and used for combat training purposes.
The Raptor pilot is probably a newbie (yes they put inexperienced pilots in the F22 too) and still needs to learn how to use the full potential of his new horse.
BTW, back in the days where the Eagle was the new wondertoy it was also beaten by more experienced pilots flying old steamboating Phantoms.
IIRC the Rafale or EF also got defeated by a supposedly inferior JAGUAR pilot from the Adla not too long ago.
Last but not least , the F5/T38 isn't exactly a slough when it comes to close combat , roll rate is something like 720°/sec if memory serves me right and ,like the good old MiG21, it is a damned small target if you have to look for it when going 600MPH.
