Project Blue Book "unidentified" case. White parachute like object with suspended humanoid form, skimming over lake in all directions.

One parachute-like object was observed by three witnesses at a lake for 30 minutes (Stoker). No sound was heard. One 5-foot-tall dwarf, wearing a green coverall and hood, was seen.

Lelah Stokes saw a white parachute like object with a suspended human like form skimming over the lake in all directions. She called in another tenant of the building. Mr. Boruszak, who also saw the object. She called the Coast Guard. The object diminished in size, till it was no bigger than a piece of newspaper, as it descended and landed. The human figure, now on the ground, was short and wore a tight fitting green one-piece suit covering also the head; he walked up and down the lakefront until the Coast Guard search boat had passed. Then the object enlarged and rose up again; the suspended "pilot" entered it, and it departed soundlessly at great speed.
