The "Chick F/O" commend didn't have anything to do with gender bias per se, simply that I can't imagine the same thing happening with two guys in the cockpit. Re-read my post, the "chick f/o" is only in the title; the point of my post is having low-time people in airliners is a really stupid idea and leads to events such as these.
I've been around long enough to see some VERY attractive female F/O's come through with VERY low time (PCL had several of these, one of which is at DAL now and was a formal model).
I watched many times as CA's would fall all over themselves for these girls, giving them all the flying legs, not getting onto them for being off on their procedures, etc.
Not saying that's the case here but, as a guy who doesn't give a rat's if you're a guy, girl, hermaphrodite, white, black, red, purple, or plaid, in that kind of weather, the CA had an obligation to make the landing in the interest of safety and didn't.
Personally, I can't think of another reason he didn't. At 24, she can't have had a reasonable amount of flight experience to be allowed to take on that kind of landing. IMHO, it's not her fault she pooch-screwed it; she probably didn't understand she was biting off more than she could chew for her experience level.
