Boeing CEO David Calhoun said the company needs to acknowledge its mistake as the aircraft maker reels from a door-plug failure that has resulted in roughly 170 of its planes being grounded and spooked its customers. 

In his first remarks since the harrowing accident, Calhoun indicated a misstep by the aircraft maker played a role. “We are gonna approach this—No. 1—acknowledging our mistake,” Calhoun said Tuesday in an address to employees just days after the incident on an Alaska Airlines flight.
