I left out stuff the the S-2 tracker ,P-2 neptune and P-3 orion and so on and such forth because it was WWII surplus and not just surplus in general. Since the Mars entered service in 1945 I guess I shouldve added it to the poll but now it's to late.
The A-26 is my choice, the TBM wouldve been second. My dad worked on the Ground when an A-26 was still being used by Butler Aircraft, the local Air tanker company. In the 60's when he was just getting into the familly business, he was in Idaho and the smoke jumpers used Ford Trimotors! They finally upgraded to a DC-3 before he moved to Washington.
