a CME could potentially do a heck of a lot more to an airplane’s electronics than the cell phones they make us turn off

If something like the Carrington Event (1859) happened today, we would be in a world of hurt. Telegraph operators reported that their telegraph units caught fire.

Such an event today would be like a worldwide EMP. Much of the world's power grid and electronic gear would get fried.

That would be awesome.

Thanks, I wasn't aware of this! I've never seen an aurora in Colorado, but I would have that year.

If that CME could fry telegraph lines it could do the same for telephone lines and electronics. It would be a mess.
