USAF has women flying frontline recently. Remember KC, Kim Campbell, aka Killer Chick, who brought back the shot up A-10 during OIF. She'd flown combat sorties over Afghanistan in OEF before that. She joined in 1993, when female pilots were accepted into the USAF.
I know that most female fighter pilots are probably in the ANG, but I think those few females on the active duty F-16, F-15E, B-2 (yup) have not been sitting still lately. I think I've also seen a female RAF pilot in a photo in some sandy place, I think she was a Harrier pilot in Afghanistan, but not sure.
I believe the Netherlands has at least one female F-16 and one Apache pilot who've been deployed.
Sure, it's still a men's world, but I think there are more females around than you might think.
On the question regarding men vs women, the thing about g-loc is true, but a well-trained short guy might even be better. I don't know about the better multi-tasking, still haven't seen any good scientific proof of that.
Regarding training/experience, the guys flying today, even in Israel, won't be around in 10 years, then they maybe have instructed the next generation, and whether they've trained a female or male doesn't matter. It all depends on the person. And besides that combat experience is only really valuable when it is used in training. Having one super experieced pilot is great, but it's better to have ten non-experienced pilots fully prepared for combat. Because that one guy might eventually get very nervous on his 100th flight, or get lazy and too courageous, or have a bad wingman that screws the mission up anyway.
