I have been interested in UFO sightings for more than 70 years. I have a collection of newspaper clippings from Dutch and Spanish newspapers . You may see them here: michaelrogge.com/Homepage//UFO%20enigma.html
According to a poll of a Dutch survey agency 4% of the respondents say that they have seen an UFO.) If we were to apply that percentage to the world's population more than 312 million people saw one! I, for one, had about ten people reporting to me a sighting.
