Boeing CEO to Step Down 

A leadership shake-up at Boeing, including news Monday that its top executive plans to step down, highlights the difficult path facing the iconic aircraft manufacturer as it tries to navigate through yet another safety crisis.

CEO David Calhoun, who has been under unrelenting pressure since a panel blew off a Boeing 737 Max jetliner during a January flight, said he would retire at the end of the year. He said the decision to leave was his and the timing would allow for an orderly transition.
