Here's my latest info on the 7th FTS T-38 calls. As usual, any corrections/additions/deletions much appreciated.
They also use LEXUS for what appears to be maybe maintenance positioning flights ?
LEXUS 1 I've also seen them use it to Randolph AFB. On your list you have LEXUS as T-38C 49Th FtS,14Th FtW Columbus AFB MS. I'm wondering if maybe LEXUS is a standard maintenance positioning callsign used by multiple bases ?
