Boeing's head of 737 Max program loses job after midair blowout

The Boeing executive in charge of the company's 737 Max production program is out of a job, Boeing said in an email to employees Wednesday. 

Ed Clark, who oversaw 737 production "is leaving the company" after nearly 18 years, Stan Deal, CEO of Boeing's commercial plane unit, wrote in a company memo, obtained by CBS News. 

Katie Ringgold, former vice president of 737 delivery operations, is replacing him, effective immediately.
