The Thunderbird-painted T-38 from the first page is Ross Perot Jr's personal steed. Saw it flying a few years back while on a Cross-Country through AFW.
I say "T-38...sort-of" because it is actually a hybrid, made from a T-38 (forward fuselage and wings), and an F-5B (aft fuselage, including the speedbrakes, a
hook, and a
drag-chute).
It has more thrust than a T-38C, but has less drag, as it does not have the PMP mod, which ruined the aerodynamics of the airplane.
The jet has an Air Force 781 maintenance book, and is titled "T-38/F-5B."
