In 1974 Ronald Reagan said, while governor of California, "I was in a plane last week when I looked out the window and saw this white light. It was zigzagging around." "I went up to the pilot and said, "Have you ever seen anything like that?" He was shocked and he said, "Nope." And I said to him: "Let's follow it!" "We followed it for several minutes. It was a bright white light." "We followed it to Bakersfield, and all of a sudden to our utter amazement it went straight up into the heavens."
