Carl Pillitteri was one of 38 Americans at the Fukushima plant when the earthquake hit. Pillitteri describes what he heard as "demonic" sounds and relates the stark fear he felt inside the turbine building that day. What is interesting and puzzling, Pilliteri, a nuclear technician could not pinpoint source of sounds in interview on PBS show Burn: An Energy Journal. The nuclear technician shares also personal impact, saying he's hardly smiled all year. The interesting questions remains: what caused an apparently non-localized, demonic-like sound?
