Boeing adds: “Our thoughts are with the passengers and crew of China Eastern Airlines Flight MU5735. We are working with our airline customer and are ready to support them.

”Boeing is in contact with the US National Transportation Safety Board and our technical experts are prepared to assist with the investigation led by the Civil Aviation Administration of China.”
