All fly by wire jets have movements based on sensors. In the F-16 a faulty AOA probe is okay. 2x Faulty AOA probes are okay as long as they disagree. 2x faulty AOA probes that agree (frozen) are a very bad thing. But the loss is just a jet with an ejected seat if it can't be fixed, not nearly 200 people which is terribly sad. The worst part is from a previous Hacker News post listed below. In particular, the "Economic Problem" which states "Boeing sells an option package that includes an extra AoA vane, and an AoA disagree light, which lets pilots know that this problem was happening. Both 737MAXes that crashed were delivered without this option. No 737MAX with this option has ever crashed." https://twitter.com/trevorsumner/status/1106934369158078470?ref_src=twsrc%5Etfw%7Ctwcamp%5Etweetembed%7Ctwterm%5E1106934369158078470&ref_url=https%3A%2F%2Fwww.zerohedge.com%2Fnews%2F2019-03-17%2Fbest-analysis-what-really-happened-boeing-737-max-pilot-software-engineer https://twitter.com/trevorsumner/status/1106934369158078470?...

> No 737MAX with this option has ever crashed. I mean there are only two 737MAXes that have crashed in total, right? It's not like we have such a huge sample to work with for this to carry that much weight.

  And the only airlines that bought the option are North American, so we are immediately confounding with pilot training differences.

    I guess when ordering a plane or a car you assume you don't need to order optional extras to stop the thing killing you.

      I mean, some safety features such as automatic emergency braking are available but optional on many cars.

        True but this is more like it may steer into a tree if you don't have the optional steering plus package.

  Would you personally board the plane whose crew didn't have this training option?

    I'm not sure I'd board any 737-MAX's at this point.

>But the loss is just a jet with an ejected seat if it can't be fixed, not nearly 200 people which is terribly sad. Not necessarily true. If that F-16 is flying over a populated area, it can kill numerous people on the ground when it crashes.
