Using our balloon for comparison, this object appeared to be about 1/4 the size of the balloon. We were climbing and about six miles northeast of the balloon. The object had a peculiar glow to it, crossing behind and above our balloon from East to West very rapidly, first coming in at a slight dive, leveling off for about a minute and slowing down, then into a sharp left turn and climb at an angle of 50 degrees to 60 degrees into the southeast with a terrific acceleration, and disappeared.
Jack Donaghue and I observed this object for approximately two minutes and it crossed through an arc of approximately 40 degrees to 50 degrees. We saw no vapor trail and from past experience I know that this object was not a balloon, jet, conventional aircraft, or celestial star.

Dick Reilly and I were flying at 10,000 feet observing the grab bag balloon when I saw a brightly glowing object to the southeast of the University of Minnesota airport. At that time we were a few miles north of Minneapolis and heading east. I pointed it out to Dick and we both made the following observation:
The object was moving from east to west at a high rate and very high. We tried keeping the ship on a constant course and using reinforcing member of the windshield as a point. The object moved past this member at about 5 per second.
This object was peculiar in that it had what can be described as a halo around it with a dark under surface. It crossed rapidly and then slowed down and started to climb in lazy circles slowly. The pattern it made was like a falling oak leaf inverted. It went through these gyrations for a couple minutes. I called our tracking station at the University of Minnesota airport and the observers there on the theodolite managed to get glimpses of a number of them, but couldn't keep the theodolite going fast enough to keep them in the field of their instruments. Both Doug Smith and Dick Dorion caught glimpses of these objects in the theodolite after I notified them of their presence by radio. This object, Dick and I watched for approximately five minutes.
I don't know how to describe its size, because at the time I didn't have the balloon in sight for a comparison.
Two hours later we saw another one, but this one didn't hang around. It approached from the west and disappeared to the east, neither one leaving any trace of vapor trail.
