This report is case #9, on the official clearance list. of 41 formerly classified Air Technical Intelligence UFO reports cleared for Maj. Donald E. Keyhoe by Albert M. Chop, Air Force Press Desk. Page 55 of the UFO Evidence (1964) lists two cases by J.J. Kaliszewski & others. The first sighting actually began on the evening of the 10th. Maneuvering UFOs were observed during balloon tracking flights. Dr. James McDonald provides a good report below, and copies of Kaliszewski's statements are provided from page 56 of the UFO Evidence also.

Moore, pilot Dick Reilly in the air, and Doug Smith on the ground (also Dorian and Zuckert). Flight crew saw the first object, brightly glowing with a dark underside and halo around it. Object arrived high and fast, then slowed and made slow climbing circles for about 2 mins, and finally sped away to the E. Soon they saw another one (at 8:30 a.m.?), confirmed by ground observers using a theodolite, which sped across the sky. (Berliner; FUFOR Index)
