broken leg. While lined up on runway 21 awaiting takeoff, a puff of smoke was observed by a ground engineer from the vicinity of engine three which he conjectured could have been due to an over-boost. The aircraft commenced its ground roll and after about swung slightly to the left, which the commander (the handling pilot) corrected with the rudder and by reducing power to number 3 and 4 engines. Once corrected full power on all engines was resumed but the aircraft swung right. The commander applied corrective rudder and reduced power to number 1 and 2 engines, but this was not immediately effective and the aircraft left the runway before straightening, parallel to the runway. Knowing that the aircraft was capable of being operated from grass landing strips, the pilot opted to continue the takeoff; however, after and at an airspeed of the aircraft swung right and its course was obstructed by a tree which was hit by the left wing and a pile of gravel which was hit by the number 4 propeller. The aircraft yawed to the right and came to rest in a cornfield; the fuselage broke into two sections aft of the bomb bay and caught fire. Historical accuracy With the exception of the aircraft names, this film is fiction based only very loosely on fact. The characters are composites, the names are not those of the real crew of the Memphis Belle and the incidents shown are supposed to be representative of B-17 missions in general. The characters and situations of the film bear little resemblance to the crew of the actual Memphis Belle, the nature of her final mission, the accuracy of strategic bombing, or Allied policy on the bombing of civilians. No optimistic official celebration on the evening before the Belle's 25th mission occurred, and there was no special welcome for the crew when the mission was over. For the fighters, seven P-51 Mustangs were used. Five of the P-51s were painted in the markings of the first USAAF Merlin-engined Mustang squadron to operate in Britain (a few months later in 1943 than the actual mission). As there were no surviving flyable Messerschmitt Bf 109s, Luftwaffe fighter aircraft were represented by Ha-1112s, a Spanish version of the Bf 109 (which were also used to represent Bf 109s in the 1969 film Battle of Britain) in mid-war generic paint schemes.
