Query: The Real Deal

In making a reservation on Southwest's website last week I noted that they are pushing two books about Southwest, one being "NUTS" and the other "THE SOUTHWEST WAY." There was no mention whatsoever about "SOUTHWEST PASSAGE", one of the best business books I have ever read. Could it be that the true story about Southwest in its early days during which the course was set for its 32 years of profitable operations, as told in SOUTHWEST PASSAGE, is so totally different from the tales told in the other books by the airline's current executives that SOUTHWEST PASSAGE has been blackballed? I know nothing about the authors of the three books, but I do know that Lamar Muse was there on the scene and can prove everything he says in SOUTHWEST PASSAGE while the authors of the other two books were probably still just gleams in their fathers' eyes.
