From the Wall Street Journal
Both crews quickly filed voluntary reports alerting airline officials and regulators about their safety lapses
I bet they did to try to get immunity. More abuse of the fine ASAP program.
The difference is that Delta would not terminate a crew for being fatigued by their roster but would when they blab in the cockpit when they should be flying.
Well done Delta! Excellent Just Culture!
