He was attending a discussion of some kind concerning UFOs. It took place in a building where the rows of chairs were close and tightly packed. He was in the audience listening to the presentation. He noticed a family of 3 sitting in front of him - Father, Mother and a child. During the lecture, the presenter was discussing possible UFO propulsion systems and was discussing how a UFO traveling in atmosphere might use a ram jet design to assist during flight. The child of the family leaned over to his mother and started to say - "But that's how our ship runs ....." The mother quickly shushed her child, but not before GW had heard what was said.
