The Armed Forces generally and traditionally are hotbeds of lewd,crude and sexist people.It goes with the territory.Moira,more than anybody,would know that,especially after spending 22 years or whatever in that environment. I believe that women are still not permitted,in Great Britain,to engage in hand-to-hand combat in the Infantry or Royal Marine Commandos,or to serve in the crews of SSBNs (Nuclear Submarines, but probably ANY submarine,to be honest ---I don't know ??).The point is, she knew the score,was / is a tough cookie, and would have been well equipped to deal with any "hassle" that may have transpired.
                  Of course,there can be no excuses whatsoever for the behaviour of some of her male colleagues at the Tower ,and I ,personally,would have been very pleased to have a, or some ,female colleague / s if I were lucky enough to be employed in such a high profile and historic position. BUT....Moira is the first of her kind,in this instance,and there were BOUND to be some difficulties to be overcome ; look what happened (inexcusably,of course,but still inevitably) ,to Lady Astor on becoming the first female MP.
      I think that, really,YOU should have been the first female Beefeater, Ruth !!
