De Rose saw a "brilliant, small round-shaped, silvery white object" which moved in a northwesterly direction as fast or possibly faster than a speeding plane at an estimated altitude of 1,000 ft or more. It stayed in view for eight or ten seconds until obscured by a cloud bank. The object reflected sunlight very strongly as though it were of polished aluminum or silver. Other than to say it "appeared round and irregular" de Rose was unable to determine its shape. It did not resemble any weather balloons he had ever seen. He stated "I can assure you it was very real."
