The P-80/T-33 had a great life. A lot of T-33's are still in service today, some using there original compressor blades made back in 1940's! Remember, this is a jet that was made in the same time period as the Me-262 (1943) and went from paper, to first flight in 143 days. Considering how little experience the US had, it turned out to be a remarkable aircraft. Able to fight toe-2-toe with the Me-262 in about every way, and did it with 1 engine. Also, remember how I said some T-33's are still flying with its original compressor blades? Me-262 engine life was about 10 hours.
