Watch Hunters in the Sky: Under All Flags, Big Friend, Little Friend, Struggle for Supremacy

Several WWII Fighter Aces recall the formation, brotherhood and bravery of the Internationals. This conglomeration of pilots of mixed nationalities, headed by the RAF, formed in the spring of 1940 to combat the Luftwaffe. Being part of the only air fighting body left in Europe during the Battle of Britain, standing between the Nazis and the world, this group of fighter aces were gathered from Poland, Norway, Australia, Czechoslovakia and even a handful of the neutral United States. Many of the surviving fighter aces recall the tactics, bravery and brotherhood of this squadron of foreign volunteers.
