In 1943, Charles Brown was piloting a crippled aircraft when he saw another plane off his wingtip. The other pilot made eye contact with Brown and escorted his plane to safety before saluting and flying away. The story gets better—for Charles Brown was piloting a US bomber over the skies of Germany, and the other pilot was a German flying ace named Franz Stigler! Stigler treated Brown as a friend even though they were supposed to be enemies.
