First hackers take down a pipeline, then a beef processor, is it possible they have taken down a airline...
Over the last few years Delta and United both shutdown their flights for reasons that did not cause suspicion from the public but if you have any network engineering knowledge you would immediately be skeptical...

Honestly when you really think about it we have surprisingly few outages. Considering that basically every major company on the planet is doing their business through networks that were built more than they were designed, every IT room in the country has half a dozen computers that nobody knows what they do, or even how to login. What’s suspicious is how much stuff works.
