Boeing boss to leave as firm faces safety crisis

Boeing boss Dave Calhoun will leave at the end of this year amid a deepening crisis over the firm's safety record.

Boeing also said that the head of its commercial airlines division will retire immediately while its chairman will not stand for re-election.

The firm is under pressure after an unused door blew out of a Boeing 737 Max in January shortly after take-off.

No-one was injured but the firm's safety and quality control standards came under renewed scrutiny.
