This is just friggin' hilarious
Vinkman, the P-38L, which is identical to the J in every way except for being a little better (boosted ailerons and dive flaps) has a much lower k/d ratio. Hmmm, let's put on our thinking caps and try to figure out why...
No, the P-38J/L is not super-impressive as a LW plane going simply by speed, turn, and climb numbers. The P-38's strengths which don't show up on paper are torqueless stability, and a very well placed gun package. And a *very* good over-the-nose view when tracking targets with those guns btw. The wing also looks like it has a high aspect ratio, which could be a help in the E-retention department during maneuvers. The J's particular strength though, are the pilots who fly them.
