   Peering through a small hole by candlelight, Carter was asked if he could see anything. His reply: 'Yes, wonderful things.'

5. Reactor four explodes at the Chernobyl nuclear power plant 1986

   The Soviet Union stayed silent until radiation set off alarms at a Swedish plant over 1,000 km away — workers' shoes triggered the detectors.
