 Zemke made progress by stressing flight discipline and teamwork, often implementing ideas of even the lowest ranking man.Despite obvious problems with the P-47 as an aerial opponent to Luftwaffe fighters—primarily its poor rate of climb, very slow rate of acceleration, and radio problems—Zemke stressed the strengths of the Thunderbolt (its excellent dive performance and superior rate of roll) and conceived tactics to match them.Rather than encouraging discontent with the P-47, as was the case in the other groups but particularly in the 4th, he turned the aircraft into a positive weapon.
