Biao's plane crashed. It is also still unclear whether Lin Biao himself planned a coup, or whether his Ye Qun and Lin Liguo had such plans and did not inform Lin Biao about it. Skeptics have claimed that Lin's decision to flee to the Soviet Union was illogical, on the grounds that the United States or Taiwan would have been safer destinations. On August 20, 1973, the Central Committee of the Chinese Communist Party posthumously expelled Ye Qun from its ranks. In 1981, the Supreme People's Court confirmed her as the principal ringleader of the Lin Biao 'counter-revolutionary group'.
