There is an additional event which recently came to mind. A coronal mass ejection, commonly known as a solar storm, can take out satellites. I wonder about the vulnerability of the GNSS system to this type of event. If you have the time, Dr. Langley, I would appreciate it if you could educate us! Thanks!
Preparedness is about planning for likely failures.
Agreed. The more unlikely the event that you prepare for, the more you look like a "prepper".
