Here are flight plans for the nice KC-135r repaints by Mark Heimer here on AVSIM. (pai_kc-135r_grissom_arb.zip)
All you have to do, after properly installing the repaints, is drop the "Traffic_Grissom_AFRC.bgl" file in to the usual flignt plans folder (C:\Program Files\Microsoft Games\Flight Simulator 9\Scenery\World\scenery) and you are done. I have included the traffic source files in case you want to fool around with it (knowledge of TTools by Lee Swordy required).
These are not official accurate real life flight plans or anything. They will get the planes into KGUS (look for the AFCAD by Matt Heden for example). They will also be showing up around here and there.
