Чжан Чуньцяо
The "Outline" allegedly consisted mainly of plans for aerial bombardments through use of the Air Force. It initially targeted Zhang Chunqiao and Yao Wenyuan, but would later involve Mao himself. If the plan succeeded, Lin would arrest his political rivals and assume power. Assassination attempts were alleged to have been made against Mao in Shanghai, from September 8 to 10, 1971. Perceived risks to Mao's safety were allegedly relayed to the Chairman. One internal report alleged that Lin had planned to bomb a bridge that Mao was to cross to reach Beijing; Mao reportedly avoided this bridge after receiving intelligence reports.
