Yang Cong, Li Jianming, and Sun Mengfei were unaware that they had been misled by the information provided by Lei Yong.
Lei Yong and Bao Enhong believed that Zhao Yi's inspiration came from model airplanes, but that wasn't the case at all. When designing aircraft, Zhao Yi did not need inspiration; what he needed was just a breakthrough.
Of course, different breakthroughs would lead to different designs, but if one were really to talk about inspiration, it would come from Lei Yong and Bao Enhong, from their validation report of the toy model airplane.
Lei Yong and Bao Enhong treated the validation of the toy model airplane as if it were just an assessment task when in fact, Zhao Yi had made improvements to various components based on their validation.
