Junkers Ju 87 and assigned to the Air Historical Branch. The aircraft was stored and displayed at various RAF sites until 1978, when it was moved to the RAF Museum. In 1967, permission was given to use the aircraft in the film "Battle of Britain" and it was repainted and modified to resemble a 1940 variant of the Ju 87. The engine was found to be in excellent condition and there was little difficulty in starting it, but returning the aircraft to airworthiness was considered too costly for the filmmakers, and ultimately, models were used in the film to represent Stukas. In 1998,
Junkers J 2 fuselage directly below the stabilizer's leading edge root. The wings had at least three different airfoil changes between root and tip, and had sections of them electrically roll-welded for stronger, more continuous bonding for greater strength. The resulting aircraft was intended to be smaller than the J 1 demonstrator, but with its steel structure, it almost equalled the J 1's completed weight. One feature pioneered in the J 2 that would also be used in later all-metal monoplanes designed and built by Junkers in World War I, was a "unitized" forward fuselage structure, combining the engine mount, wing roots and
