I've seen some articles that say if, and when, we have another solar storm like the one in 1856, or when was that one that set telegraph offices on fire? 1885? Dummie me. Anyway, that would knock out our satellites, cell phones, and who-all knows what else.

I believe our modern life is a fragile thing.

How would all those planes land with zero ground contact? Would their onboard systems still work?

Oooo, better go feed my chickens. I miss the old days where I didn't know so durn much science news. Spent two hours looking at CNN live waiting for the tsunami. Owell!
