Yeah... I had forgotten about the airports needing to recalibrate these days.
We do know that these things happen... but we don't know whether they happen quickly or over time. That would have a lot to do with the long term impact. And... yes... these are not necessarily extinction events.
The upcoming alignment with the center of the galaxy could be a catalyst for such an event. And... it could NOT BE a catalyst.
We'll see.
