Here is a map showing the location of sightings of black triangular craft in the United States, like those seen in Belgium. The data was taken from three major UFO reporting centers. The map shows the location of more than 700 sightings of a Flying Triangle (denoted by a red Triangle) and the relationship to nearby towns and cities. The circles denote the positions of nearby AFBs. It can be seen that the locations of the AFBs in many cases
overlap with populated areas. And many of the Flying Triangle sightings also occur in or near populated areas. There is video evidence to support two cases near San Diego and Tampa.
