As for the Bolivian T-33 I belive they are still in service. There was an article in “Combat Aircraft’ a few mouths ago. As far a WWII requirement the P-80 was designed in 1943 and flew in 1944. The original designation for the T-33A was TF-80C and was changed for political/budgetary reasons.

What about the S-2 Tracker? First flight 1952.

indeed! And don’t forget the C-1 Trader. (Now called KC-2 Turbo Trader)

I was thinking of the Hunters still in service in Lebanon.
