Lastly, I think both parties in this particular incident used inappropriate language.
I think the adverse reaction to the language in this incident is overblown. Due to the initial transmission being blocked, it’s not clear if the controller even comprehended LH’s F-bomb. And the F-bomb was clearly not directed at the controller. The analysis in post #71 indicates that the FAA management at NORCAL had no issue with the controller’s language or procedures.
I think LH’s F-bomb and “Ha!” interjection were indicative of his embarrassment and frustration in having to publicly declare that, as an international captain flying a state-of-the-art airliner, he was not allowed to execute a procedure that virtually every other arrival into SFO was safely executing. And to cap it off, he is then left to publicly divert to the inferior of the cesspool of San Francisco.
