Solar radiation like solar wind, or sunlight? They don’t say.

“Analysis of a recent event” I presume they mean a Coronal Mass Ejection.

  I feel like the event was something that happened to a plane. That said, I wouldn't think sunlight would be penetrating to the chips running the plane.

    Gamma rays penetrate everything and have definitely been known to disrupt computer circuits.

      Yes, which is why the solar flare scenario makes more sense.

      > At least 15 passengers were injured and taken to the hospital after a sudden drop in altitude on the flight from Mexico was forced to make an emergency landing in Florida, US aviation officials said at the time. I’m surprised passengers are allowed to unbuckle for so much of each flight. You can get injured while buckled it, but that seems less common.

        The flight attendants/safety card will tell you to stay buckled whenever seated, even if the seat belt sign is off, but many (most?) people will ignore that guidance and stay unbuckled for as long as they are technically allowed. Only aviation professionals or recovering flight phobics like me who have watched every episode of Air Crash Investigation will take proactive safety measure of their own accord. To normies it's all just a pointless hassle.

        I stay buckled and I’m just a “normie” not afraid of flying that understands turbulence doesn’t always happen in a bell curve with some notice. Not sure if that makes you feel any better? :)
        MaxfordAndSons 10mo ago
        Having an understanding of the bell curve of turbulence makes you a bit more advanced than a normie on the aviation knowledge bell curve imo :)

        People have different priors for bad things that can happen on a plane. If you’ve experienced turbulence you’ll probably buckle up.

        I'm not flight phobic but I still stay buckled all the time when I don't need to move. It's a very little nuisance.

  There was a very large CME ten days ago. The NOAA scale had predicted a high likelihood of disruptions, and had specifically suggested that spacecraft and high altitude aircraft could be impacted. https://www.swpc.noaa.gov/noaa-scales-explanation https://www.swpc.noaa.gov/noaa-scales-explanation https://kauai.ccmc.gsfc.nasa.gov/CMEscoreboard/prediction/detail/5065 https://kauai.ccmc.gsfc.nasa.gov/CMEscoreboard/prediction/de...

    FWIW the "industry sources say" line on the incident is that it occurred on 30 October[1], so further back than ten days ago but of course there may have been other CME incidents at that time. The European Agency Aviation Safety Agency [2] instruction describes the characteristics of the incident but not the date.

Would guess "cosmic rays". Sun Microsystems had a batch of UltraSparc servers that were very sensitive to it, and it was a big issue. https://docs.oracle.com/cd/E19095-01/sf4810.srvr/816-5053-10/816-5053-10.pdf https://docs.oracle.com/cd/E19095-01/sf4810.srvr/816-5053-10... https://en.wikipedia.org/wiki/Cosmic_ray https://en.wikipedia.org/wiki/Cosmic_ray
