The China Eastern Airlines Corp. jet that crashed Monday was traveling at close to the speed of sound in the moments before it slammed into a hillside, according to a Bloomberg News review of flight-track data.
Such an impact may complicate the task for investigators because it can obliterate evidence and, in rare cases, damage a plane’s data and voice recorders that are designed to withstand most crashes.
The Boeing Co. 737-800 was knifing through the air at more than 640 miles (966 kilometers) per hour, and at times may have exceeded 700 mph, according to data from Flightradar24, a website that tracks planes.
