Seriously though, it's something we do need to be considering, but I don't really think there is cause for alarm in the long term. The biggest problem, as stated in the article is electronics equipment, seeing as we are far more reliant on it now than we were the last time storms were this strong. As to whether the impact will go so far as terrestrial objects I don't know, the last one certainly affected the telegraph service at the time, we will have to wait and see.
