This post is the first I’ve heard of this, and I’m confident in declaring it pseudoscientific bullshit.
I present to you: The Carrington Event. In 1859, the Earth was directly hit by a coronal mass ejection from the Sun. This caused the strongest geomagnetic storm in recorded history. Miners in the American rocky mountains woke up in the middle of the night because the Aurora Borealis was so bright they thought it was morning. Currents induced in telegraph wires caused sparks and fires. A telegraph line from Boston Massachusetts to Portland, Maine was able to operate for hours with no power connected at all; the geomagnetic storm induced enough current in the telegraph lines that the operators were able to pass traffic for hours without any batteries connected to the circuit at all.
There is no mention of people dying from unexplained heart attacks at the time. If solar or geomagnetic storms could magnetically disrupt blood flow, you’d think the largest geomagnetic storm we know of would have been associated with an uptick in recorded cases. But it isn’t.
THAT SAID. I do believe that solar flares, CMEs or other such events can and do have an effect on the health of organisms on Earth including humans. I spent most of my time in aviation meteorology class studying the troposphere so my understanding of the high atmosphere isn’t as strong, but…bombard the high atmosphere with particles from the sun, some chemistry can happen which disrupts the ozone layer, more UV light makes it to the surface, and we get more sun burns and skin cancers. However, as far as I can tell, Thomas Midgley Jr. had more of an effect on the ozone layer than any recorded solar flare has.
The 172 was in production from the mid 1950’s to 1986, and then they resumed production in 1996 to the present day. It is my understanding that the modern Skyhawk is technically a different aircraft, different type certificate and few interchangeable parts, but it’s still the Toyota Corolla of airplanes.
