On Monday, a China Eastern Airlines passenger jet carrying 132 people crashed in the mountains in the south of China. The China Eastern Airlines Boeing 737, which had 123 passengers and nine crew members onboard, tragically crashed in the mountainous region.

The plane was en route from the southwestern city of Kunming, capital of Yunnan province, to Guangzhou, capital of Guangdong, bordering Hong Kong. China Eastern Airlines stated that the cause of the crash is currently under investigation.

According to Flightradar24, the passenger jet descended at 31,000 feet a minute. The plane began “suddenly descending” while in the cruise phase.
