As per the Jewish pilot controversy, here's what Wikipedia says. Although I don't think it's determinant information, I find it interesting.

Palestinian contribution
The RAF's official "Battle of Britain Roll of Honour" recognises 1 Palestinian as having fought in the Battle of Britain: Pilot Officer George Ernest Goodman (42598 ), born in Haifa, Palestine (now Haifa, Israel). The Palestinian contribution is also sometimes described as the "Israeli contribution", although the State of Israel was not proclaimed until 1948. PO Goodman's parents were British Jews, he carried a British Passport and was educated at Highgate. He is therefore sometimes recorded as a British airman.

At least 32 (probably 43) Jewish airmen took part in the Battle of Britain (just over 1% of participants). Over three-quarters were British Jews, the rest fighting in the American, Belgian, Canadian, Czechoslovak, Polish and South African contingents (Martin Sugarman).
