Commemorating the 66th anniversary of the Roswell, New Mexico, UFO incident, Internet search giant Google came up with a special interactive `Doodle' - a point-and-click adventure game - for its homepage on July 8.

The Roswell UFO incident dates back to early July 1947, when the US encountered the one of the first unidentified flying objects which fell from the sky into a ranch in Roswell, New Mexico.

Though the exact date of the UFO crash at the ranch is not known, the metallic debris of the object was spotted by the ranch's foreman Mac Brazel, who informed the sheriff's office, which further sounded an alert to Roswell Army Air Field's Major Jesse Marcel, who in turn alerted the Eighth Air Field.

A press release about the UFO was issued on July 8 by Colonel William Blanchard, Commander of the 509th Bomb Group, from the local military base. The press release said that a "crashed disk" had been recovered from the Roswell ranch.

To commemorate the UFO incident, the Google logo on the search page has been replaced with black-and-white alien in a flying saucer. The logo can be clicked on by the visitors to the homepage to play an interesting adventure game, in which the player has to help an alien recover the missing components of the flying saucer. During the process of searching for the UFO's missing parts, players can explore a farm in Roswell, feed chickens, and grow a magic bean stalk!
