MoD's Error Leaks Secrets of UK Nuclear Submarine

Tasha26 writes "UK's Ministry of Defence admitted that secret information about its nuclear powered submarines was leaked on the internet by mistake. A 'technical error' (i.e. turning the background colour of certain text to black) meant that sensitive blacked-out parts of the online MoD report could be read by anyone who copy-pasted it into another document. This accidental leak reveals, among many other things, how easy it would be to cause a Fukushima-style reactor meltdown in a sub, and details of measures used by the US Navy to protect its own nuclear submarines."
