December 20, 1942, en route to bomb the German aircraft factory at Romilly-sur-Seine, about 50 miles south-east of Paris, the 91st Bomb Group's B-17s come under attack by Luftwaffe fighters. The Memphis Belle holds steady, skippered by Bob Morgan, as an Fw190 comes flashing through the formations at a hair raising 400mph with 20mm cannons ablaze. A second enemy fighter peels over to begin its attack high off the starboard wing.
