Completely unrelated and due to a design failure by the rpi folks.
Is it really so unrelated? Isn't it a case where a similar phenomenon -- radiation impacting a computer calculation -- happened and it's one we can all relate to more easily, and reproduce if we cared to, than high altitude avionics? Not necessarily disputing but it just seems like a relatable case that helps me understand the issue better. If it's a radically different case somehow I'm interested to learn.
No, because it's a completely different kind of radiation.
Different band, sure. Same principle, right?
The difference between ionizing and non-ionizing radiation is quite different. But for much of the radiation effecting electronics at high altitudes it's largely subatomic particles.
And of course you can block the type radiation that caused problems for the rpi with a good piece of paper.
