The data recovered from the black box of the China Eastern Airlines jet suggests that the crash was intentional. Boeing 737-800 jet crashed in the Chinese mountains of Guangxi on March 21 killing all 123 passengers and nine crew members.
The information from the box indicates that someone in the cockpit intentionally crashed the plane, reported the Wall Street Journal. The US officials' preliminary assessment did not find any indication of technical malfunction.
The Boeing 737-800 jet was going from Kunming to Guangzhou when it took a sudden plunge from cruising altitude and crashed in the mountains. As per data from Flightradar24, the jet was flying at 29,000at a speed of nearly 700 mph when it crashed. Air traffic controllers and nearby planes sent repeated calls to the pilots during the rapid descent but received no response.
According to experts, 737-800 planes have been in service since 1997 with a strong safety record and China Eastern resumed its use in mid-April with no additional technical recommendations, reported Reuters.
Chairperson of the National Transportation Safety Board of the US, Jennifer Homendy, said board investigators travelled to China on May 10 to assist in the investigation. "They found no safety issues with Boeing".
China Eastern after the preliminary investigation said the pilot and co-pilot had been in good health prior to the flight. They also suggested the cockpit security was unlikely to have been breached because no security code was sent before the accident.
The WSJ report stated the assessments are preliminary and more information may change the understanding of the incident. The airline had referred the investigation to officials and said it wasn't responsible.
