We're all talking about the physical limitations of women in frontline roles, but a far greater and more general problem with women in the workforce, particularly in leadership roles, is our inability as a species to hold females accountable for their performance in the same way we hold males accountable. Cheatle is a perfect example - in response to catastrophic failure causing actual death she can simply bluff it out with inane statements about sloping roofs, while a male leader would have resigned or been forced to resign by now. The effect of such tolerance towards women's failures is compounded when you consider the morale sapping effect on competent men (and women) working under them. It's the same lenience towards women we see in the justice system, with grossly unequal penalties for men and women for similar crimes.
