P-80 was in the PTO?!? 
No, a squadron was formed in the US in july of 45, however none went overseas, the squadron wasn't ready for operational readiness, and the war ended before it was even near being shipped, most likely it wouldn't of been stationed in Okinawa even in wartime conditions (assuming downfall went through, because the closest airbase would of been Okinawa, and the P-80s lack of ranger would of been a factor.
However it would of been deployed, most likely Philippines, then shipped elsewhere.
