UFOs Expected At Royal Wedding, Says Retired Air Force Major George Filer

UFO sightings is a family tradition, Luckman speculates. He also says Prince Charles was chased by a UFO in 1989 while flying back to Britain from the United States.

Willis says his research shows that the queen has shown interest in crop circles, especially during the 1960s and '70s when they were destroying crops.

"She was even photographed inside a crop circle, but I think her interest was more because this was something that was affecting citizens than her being a real fan," Willis said.
