WASHINGTON (Reuters) -Boeing CEO Dave Calhoun acknowledged errors by the U.S. planemaker as more than 170 jets remained grounded for a fourth day, telling staff the company would ensure an accident like the mid-air Alaska Airlines panel blowout "can never happen again."
The company's top planemaking official, Stan Deal, also told a somber town hall meeting at its Renton, Washington 737 factory that Boeing acknowledges "the real seriousness of the accident" as it launches checks into its quality controls and processes.
