On Wednesday, the Yichun government downgraded the death toll from the crash from 43 to 42 after a body that was torn apart was previously counted twice, according to the state-run Xinhua news agency. Fifty-four people survived.

Some passengers were thrown from the plane upon impact, according Xinhua, which cited the head of the publicity department of the Yichun city committee of the Communist Party of China.
