In contemporary history, the 3rd (third) millennium is the current millennium in the Anno Domini or Common Era, under the Gregorian calendar. It began on 1 January 2001 (MMI) and will end on 31 December 3000 (MMM), spanning the 21st to 30th centuries.
Ongoing futures studies seek to understand what will likely continue and what could plausibly change in this period and beyond.

Due to tensions between The United Kingdom, The Soviet Union, and Nazi Germany, the circumstances of his death has led to disputes over whether the crash was deliberate or not. The official conclusion by the British government is that the crash was accidental.

In 2008 an investigation was opened by the Commission for the Prosecution of Crimes against the Polish Nation of the Institute of National Remembrance, and concluded in 2013 that there is not enough evidence to prove or disprove the sabotage theory.
