WASHINGTON: Boeing officials "inappropriately coached" test pilots during recertification efforts after two fatal 737 MAX crashes killed 346 people, according to a lengthy congressional report released on Friday.

The report from the Senate Commerce Committee Republican staff said testing this year of a key safety system known as MCAS tied to both fatal crashes was contrary to proper protocol.
