No correction or apology that I have seen, though the Letters Editor may have written privately to the professor. Perhaps Saturday's Feedback column may refer to it, but I suspect that The Times does not want to highlight the error.
As for the skimpy knickers and the host - well, the feminine forms (of words) have been extensively discussed here before. Probably host/hostess is going the same way as actor/actress, so 'host' may be apposite in the clue anyway. How quaint 'air hostess' sounds! I think it would be taken as an insult nowadays.
