Rumours have been doing rounds online that the co-pilot "might be responsible" for the crash, attributing it to the data from black boxes, with some believing that the CAAC will require flight crews to undergo mental health monitoring.
Black boxes are designed with the aim of identifying causes and helping prevent accidents and the first of two black boxes have been recovered from Chinese plane crash site.
Just before it slammed into the hillside, the China Eastern Airlines plane that crashed on Monday was travelling nearly at the speed of sound, as per flight-tracking data.
The China Eastern Airlines Boeing 737-800 was flying at 29,000 feet (8,800 meters) on Monday afternoon when it suddenly nosedived into a gap in the mountains outside the southern Chinese city of Wuzhou.
