Yes, but in FS9 that goat needs to get trained.

The flight dynamics are great in FS2002 but they just don't translate as well in FS9.
To me, the T-38 needs to feel like a trainer. Tricky to handle for the new folks but only a little more tricky than an actual fighter.
What I wound up doing was to swap-in the .air file from the Virtavia F-5 Freedom Fighter. Its been a while but I think I also replaced some stuff in the aircraft.cfg file that was "donated" from the F-5.
To be clear, its going to depend on how much you fly it.
