The date is only approximate.  However, it is interesting to note the spate of sightings in southeast New Hampshire during the summer of 1965, culminating in the dramatic sighting near Exeter (Kensington), NH, on 03SE65, known as the "Incident at Exeter."   That case was the first one investigated by Peter Davenport, presently the Director of the National UFO Reporting Center.  PD
