If the Czech version says: To je neuvěřitelně rychle. kdy jediná zranitelná technologie byl telegraf. jsme ještě nezažili další dokonalou sluneční bouři.; hence the English version should say: That's incredibly fast. Fortunately, the perfect solar storm took place in 1859, when the only technology vulnerable to the onslaught was the telegraph. Since the era in wich we've become dependant on high technology, we've yet to see another perfect solar storm.
