China ended a record of 4,227 safe flight days in the history of civil aviation worldwide after a China Eastern Boeing 737 with 132 people onboard crashed Monday afternoon in South China's Guangxi Zhuang Autonomous Region, causing a mountain fire.

Although no casualties have been reported yet, it is believed that there is little chance of survival for those onboard, as flight data showed the plane lost its radar information two minutes after it suddenly descended from cruising altitude of around 8,869 meters. An unverified video circulated online showed the plane almost vertically fell to the forest.
