I always thought that these stories were myths put out by USAAF crews convinced that the Luftwaffe used such tactics! Having said that it wasn't unknown for Allied aircraft to shoot at each other. Perhaps the crew from the lone B-24 was just trying to get in formation with another Bomber Group for self protection and other B-24s in that Group shot at the stragler, giving others in the formation the impression that it was firing at them!
