The day a chivalrous German flying ace saluted a crippled US bomber and let them fly to safety instead of shooting them down.
The bombing mission targeting a German munitions factory had been a success, but Second World War pilot Charlie Brown's attempts to get home safely seemed doomed to failure.
His B-17F bomber had been attacked by no fewer than 15 planes - leaving one of his crew dead and six wounded; 2nd Lt Brown himself had been knocked out and regained consciousness just in time to right his plane after it went into a dangerous nose dive.
But as he tried to return from the raid on Bremen to the safety of Allied territory after the mission on December 20, 1943, the danger was not over.
Brown soon had another major concern: a German plane was flying directly next to his own - so close that the pilot was looking him directly in the eyes and making big gestures with his hands that only scared Brown more.
