Mr. Minozewski observed a strange metallic disk on three occasions thru the theodolite while making his pibal observation during a six-months period. Mr. Minozewski last observed the disk in April 1947 at 1100 E Pibal Observation when the balloon was at 15,000 ft. He followed it for 15 seconds. It was moving on level flight from east to west to the far north of the station. The object was a metallic like chrome-shaped something like an ellipse with a flat level bottom and a dome like-round top. The disk appeared below the (westward) balloon, was much larger in size (in the instrument) and shown like silver. It was impossible to estimate the height or speed of the disk except that it appeared to be moving rather rapidly. Miss Baron, a co-worker observed the disk when her balloon was at about 27,000 ft. She thought the color to be a dull metallic luster.
