Black Thursday

From Tardis Wiki, the free Doctor Who reference

Black Thursday was the name of the cover story issued by the British government to hide the true nature of the Nestene's attempted invasion of Earth in the 1970s. It was used to explain that the Auton shop window dummies coming to life and the resulting deaths that followed this incident were because of terrorists, which many citizens theorised were of the Irish Republican Army. (PROSE: Who Killed Kennedy, TV: Spearhead from Space) A later Nestene invasion (TV: Rose) which occured on 5 March 2005 would be covered up in the same way. (AUDIO: One Rule)
