Can Boeing get back to its glory days?

Boeing executives spent years after two fatal 737 Max crashes trying to convince Wall Street, regulators, airlines and the flying public that they had an eagle eye on quality, reliability and safety.

Then on Jan. 5, about six minutes and 16,000 feet into a packed flight out of Portland, Oregon, a door plug blew out of a nearly new Boeing 737 Max 9. The panel was missing key bolts that hold it in place, which the company had removed to fix damaged rivets, according to early accident reports.

No one was seriously injured, but the harrowing flight jolted Boeing’s leaders back into crisis mode. It also reignited scrutiny and skepticism from the same groups the iconic plane-maker spent years trying to win back after the two Max crashes.
