  1. British and French planes ✔
  2. Brand new American fighters
  3. Mostly German planes they captured

Why: The U.S. had very few military planes when it entered the war. Congress promised thousands of new aircraft, but American squadrons ended up flying planes built in Britain and France.

Huh, didn't know that: By 1912 the world's major countries had all formed military flying services.
