I saw online this weekend that Southwest Airlines had retired Texas One, a jet painted up in Texas colors.  Texas One is a 737-300 and Southwest is accelerating the withdrawal of the 300 Series jets.  It flew out of Dallas to a facility that will break the jet for parts.  By coincidence, I happened to shoot this very jet the day before when it arrived at SFO.  I had no idea that it would be at the end of its career.  Nice surprise.  For those that like the colors, fear not.  I hear that Southwest will be painting another jet in this scheme before too long.
