I know I will catch hell for this, but, in my experience (Military, and Major US airline) I've found that the women who make it this far are usually very good pilots as able as any man! However, Women definately leave the business much more than men,I've known alot of women, who went through the rigors of Air Force Pilot Training, only to quit to have kids and never return, or like one did, she opened her own shop in Colorado selling aromatherapy supplies! My theory is these women enjoyed the challenge of learning to fly, getting on with a major airline etc...but then it became "work" and wasn't "fun" any more. Most men can't just quit like this, too bad!! probably many of us would like to at this point in aviation's history. Also I can tell you from an instructors POV that women tend to fixate while flying and at times seem to lose the "big picture" more often then male pilots. Give me a second to put on my helmet and jump into the foxhole!!!!!
