: CS1 maint: multiple names: authors list (link)Trotz aller Sorgfalt habe der flugfähige Nachbau der "Weißkopftaube" leider 'keinerlei Beweiswert', kritisiert der Leiter der Luft- und Raumfahrtabteilung des Deutschen Museums, Werner Heinzerling. Beispielsweise wurden die Bambusholme der Tragflächen mit Glasfaserkunststoff verstärkt und anhand umfangreicher Tests – wie sie Weißkopf nicht möglich waren – der ideale Schwerpunkt der Maschine bestimmt. ... Auch die Verwendung moderner Flugmotoren verfälscht nach Ansicht des Aerodynamikers und Flughistorikers Heinzerling die historischen Tatsachen. [But in spite of all diligence, the flyable reproduction of the Whitehead Dove was 'devoid of any conclusiveness', criticised Werner Heinzerling who is director of the aerospace department at Deutsches Museum. E.g. the bamboo beams of the wings had been enforced with fibre glass, and the aircraft's ideal centre of mass had been determined by extensive tests – which were not available to Weisskopf. ... Also the use of modern aircraft engines distorts the historical facts according to aerodynamics expert and aviation historian Heinzerling.]
