How about a jet fighter other than the 262. The p80 was actually late ww2 but it was ww2.
If I remember correctly, there were
four P-80s sent to the ETO just before the war ended, two to England and two to Italy, with the pair in Italy making a single flight in what was technically still a combat zone, but did not fly in any area where they might encounter German aircraft. Hardly an operational fighter.
