The aircraft was named for Dorothy, wife of the pilot, Capt. Robert Knox as he nicknamed her 'Pickelpuss'. On August 17, 1943, the 481th squadron was the lead for the 100th Bomb Group which was assigned to bomb the Messerschmitt factory at Regensburg, Germany.

Shot down by enemy fighters (Hauptmann Von Bonin,Oberleutnant Barte and Leutnant Witzke), the aircraft crashed at Herbesthal Lontzen, 500 meters west of Schmalgraf, near Kelmis, west of Aachen, Belgium.

Much has been written about the 'Legend' of the 100th Bomb Group being 'picked on' or singled out by the Luftwaffe for punishment because a 100th Group B 17 had, during the Regensburg raid, pulled out of formation with battle damage and then lowered its wheels in a supposed token of surrender. Then, when approached by several Luftwaffe fighter aircraft, its gunners were supposed to have opened fire and shot down several of the German planes. 

Crash time 11.40 Hrs. MACR 667
