The Exchange Student arc at the end of season 2 is one of my favorite parts of the show because it focuses so much on 39. Most fans remember the B-plot where 40 and 51 had to get properly fitted RAF uniforms (because reasons) and kept failing (because fanservice). That one shot of P-51 in a too small RAF uniform sums up pretty much every Fly Girls wall scroll I've seen at a con.

But the A-plot about 39 going from an underachiever on the American side to one of the Russian all-stars? Really some of the best writing in the early seasons. The arc's concluding episode, "Fight On, Kobrastochka!" where 39 and Yak team up against the Germans and totally clown Fw 190 is one of the most heartwarming bits of asskicking in modern anime. :)
