Mrs Pauline Coombs, her mother, and her four children were driving back to their Ripperston Farm home when her mother called their attention to a whitish disk like object over their car, flying in the direction of the sea; curious the women drove in the direction of the shore, then crossed two fields to get to the water's edge. Several hundred yards off shore is an outcrop of rock called Stack Rocks, rising up 80 to 100 feet from the water. They could not see the UFO, but they did see two humanoid figures walking about on the rocks. They were dressed in silvery outfits similar to a frogman's wetsuit; their heads (or helmets) were extremely large and rectangular in shape, rounded at the corners, with no observable features. They appeared to be looking for something. A "door" appeared on the right hand face of the rocks, sliding alternately open and shut like the door of a dumbwaiter. One of the figures entered this doorway and appeared to descend a stairway, disappearing in the darkened interior, and then reappearing once again. The stairway was not visible to the viewers. On this final descent, the door closed and disappeared from view. To the left side of the rocks, the second figure appeared to "walk" out over the water's surface, finally disappearing behind the left side of the rocks. The display had lasted for 15 minutes.
