From the Wikipedia entry for Lin Biao:
Lin became instrumental in creating the foundations for Mao Zedong’s cult of personality in the early 1960s, and was rewarded for his service in the Cultural Revolution by being named Mao’s designated successor as the sole Vice Chairman of the Chinese Communist Party, from 1966 until his death.
Lin died on 13 September 1971, when a Hawker Siddeley Trident he was aboard crashed in Öndörkhaan in Mongolia. The exact events of this “Lin Biao incident” have been a source of speculation ever since. The Chinese government’s official explanation is that Lin and his family attempted to flee following a botched coup against Mao.
Wagner chief Yevgeny Prigozhin presumed dead after Russia plane crash – BBC
Wagner boss Yevgeny Prigozhin was on the passenger list of a jet which crashed killing all on board, Russia’s civil aviation authority has said.
Earlier, Wagner-linked Telegram channel Grey Zone reported that the private plane, which belonged to the 62-year-old, was shot down by air defences.
Grey Zone posted later on Wednesday that Prigozhin died “as a result of actions of traitors of Russia”.
Prigozhin led a failed mutiny against the Russian armed forces in June.
