The China Eastern Airlines Corp jet was flying a normal route to Guangzhou when it suddenly jumped at cruising altitude and took off.
That’s all known about the unusual crash that killed 132 people on board Monday in China’s worst commercial air crash in more than a decade.
According to veteran crash and previous crash investigators, although there have been a number of crashes in which a plane plummeted from cruising altitude, few, if any, have been reported.
“It’s a strange record,” said John Cox, an aviation safety consultant and former 737 pilot. “It’s hard to get planes to do this.”
As investigators search the plane’s two crash recorders and begin searching for clues, they will try to determine why the plane made such a sudden and severe dive. As such, this is different from previous accidents.
They will look at the weather the plane was in, whether the pilots made any distress calls, any hints in the wreckage of possible problems, and detailed records. crew details.
