Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Planes wouldn't just fall out of the sky anyways lmao. Even if planes lost communications completely they are still operational flying machines. It would just be very difficult to coordinate planes landing at that point. I don't know about the protocols, but I'm sure there exist failsafes to coordinate air traffic in the event of radio communication loss.

It would be a bit more serious than a loss of communication. The electronics in the plane would be completely melted. Including the ones responsible for controlling the plane.

Airplanes are designed to withstand the current, voltage, and EMP effects of lightning strikes, whose local fields are several orders of magnitude more powerful than anything the sun has ever thrown at the earth.

Any solar-originated pulse strong enough to "completely melt" any electronics in the plane will kill everyone and everything on the daylight-side of the planet, and probably strip the entire atmosphere.

Why and how would the electronics in an airplane be melted? Airplanes are naturally a Faraday cage, and all the components are going to be EMF shielded anyways.

The only thing an airplane would need to worry about with a solar storm is the increase in radiation exposure, and even then it's only relevant for the Flight crew who have limits on how much radiation they can be exposed to per OSHA.

That's not how earlths magnetic field induced current works...

The conductors on a plane are short, the induced current is tiny. Significant currents are produced in long conductors (transmission wires). Severely damaging the infrastructure they connect to, and potentially themselves.

True and I didn’t mean to imply it. Went for the hyperbole you tend to see and did a poor job with it after all.
