Did it take lots of physical strength to fly WWII war planes?

3. As with most things, I believe the correct answer is "it depends"

Depends on the aircraft, and the operating conditions.

Did women fly wwii aircraft at all? Yes. Certainly.

For the US, see the WASP.

But in combat? No. Wasn't allowed.

In the USSR, officially women were not allowed to be combat pilots. In reality, there were some and they were well known enough that they earned a nickname from the Germans, the Night Witches.

People's physical abilities vary a great deal within a gender, so there would have been capable women and incapable men -- just like there are today. The policies of excluding women categorically are social and political ones. Also, in wartime requirements tend to become variable when what is needed and what is available are out of sync, as demonstrated by the Night Witches.
