A famous UFO sighting, the Roswell UFO incident, sparked interest in aliens. This event happened in 1967, New Mexico, when speculators thought that the US military had captured a flying saucer, but the military reports, it was just a surveillance balloon. Conspirators still believe that was not a balloon, rather an alien ship.
