The technology is not working because of a lack of investment, that much was obvious at Christmas.

Factually describing the outage doesn’t remove responsibility; whoever didn’t take the first crisis seriously enough will face it soon enough. Right now, they need engineers, the FAA, flight controllers, etc. to unstuck them. Then there will be a blameless diagnostic. Then heads will roll and I’d be surprised if the most demotion won’t be a general manager.
