Spring break for hundreds of thousands of Delta Air Lines passengers was disrupted by April thunderstorms in Atlanta that led to an epic OM meltdown, writes The Wall Street Journal (May 4, 2017). At the root of 4,000 canceled flights: telephone busy signals. The biggest problem was that Delta’s 13,000 pilots and 20,000 flight attendants calling in for new assignments couldn’t get through to the people in Atlanta on the front lines of rebuilding the schedule.
