This is the BO-2 'sugar falcon' one of the most feared fighters of WWII. Now dont let its colors and callsign get in the way of the fact that this fighter belongs to a pilot known only as the sugar falcons pilot, when he got his callsign he was sad at first but took advantage of this callsign and painted his BO-2 pink overnight, his idea was that when enemy fighters saw their opponent which in this case would be the sugar falcon,the enemy would get over confident and would laugh at their enemy not knowing that the pilot was very intelligent, and when they'd call for backup,the recieving end of the call eould think it was a prank delaying the backup BUT if they do send backup, which they normally do, all they'll find is the remains of the pilot who called for backup, the germans started to call this pilot, "the pink crusader" and most germans learned to fear that name until the end of the war.
