Figured I'd help the effort by adding a few episodes to the list:

- "Catch A Falling Star" (Episode 502): When an opening on Columbia East's fighter team presents itself, a pair of eager young girls compete to see who will usher in America's jet age. Guest-starring P-80 "Star" and P-59 "Comet."

- "Bug Hunt" (Episode 520): In order to finally put V-1 out of commission, Britannia sends Tempest and newcomer Meteor into the fray.

- "Bodenplatte" (Episode 601): With Columbia East and Britannia Academy operating unhindered in Europe, Germania's Headmaster gambles everything on one major offensive to turn the tide.

- "Ride of the Valkyrie" (Episode 615): With Germania's team in shambles and her sisters defeated, Me-262 flies off into battle one last time.

- "In At The Death" (Episode 620): The Atlantic Conference comes to a sudden climax, leaving the girls of Gymnasium Germania left wondering what they were fighting for.
