On related note we had this Sunday evening power outage in big part of Prague, lasting around half an hour (second one in less than 4 months, previous lasted around 40 minutes and was due to some power station equipment failure, some gas insulation or something). Funniest thing is the cause for this Sunday outage - power company spokesman said it was caused by (NOT hot air) balloon crashing into powerlines! So never underestimate coincidence (Bulgarian lottery) and/or incompetence, though it was most likely Americans, if we are serious.
