Google has marked the 66th anniversary of the infamous UFO incident at Roswell with an elaborate Google Doodle.
The homepage graphic celebrates the legendary moment when it is claimed that an alien craft crashed in the Nevada desert.
Several witnesses said that they saw a flying saucer in the sky above Roswell, New Mexico on or about 8 July 1947.
A series of events followed which have since been exhaustively examined and investigated by enthusiasts - and are still debated today.
They involve a press release which was issued by a local US military facility claiming alien debris had been recovered from various points where the crash occurred. It was also reported that alien bodies were found at the scene and taken away by authorities. The US Air Force later claimed the debris was from an experimental high-altitude surveillance balloon, whereas UFO 'experts' suggest it was of extra-terrestrial origin.
The incident was not world-famous until 1978, when physicist Stanton T Friedman interviewed Major Jesse Marcel (above), who claimed the debris was in fact from an alien craft, and that its discovery had been covered up.
The US Government has always denied the claims, and the US Air Force went so far as to release a 'definitive' report on the subject in 1997 ('Case Closed: Final Report on the Roswell Crash').
But the incident is still debated, and the evidence still pored over by those who remain convinced that not only are we not alone in the universe, but that our neighbours came to say hello 66 years ago.
The Google Doodle marks the occasion with a mini-game in which users have to control an alien in the desert and complete various tasks.
