Boeing CEO Dave Calhoun, along with two top executives, announced they will step down from their positions at the company following a string of accidents that have led to major safety concerns from the public.

In a memo posted to the company’s website on Monday, Mr Calhoun said the Alaska Airlines Flight 1282 incident was a “watershed moment” for Boeing and that he would leave the company after this year as the company looks to commit more safety and quality assurances.
