My dad saw three disc-shaped objects hover a few hundred feet off the ground for around a half hour and then suddenly speed away out of sight within a couple seconds. ....in the Catskills, NY, summer of 1947. ....a year, incidentally, when a great many UFO sightings/encounters were reported.
Thanks.
Much appreciated.
[Obviously, your dad was halucinating from all that clean fresh air back then.
