Staff sergeant Clifford B. Hart, a flight engineer, and 2 others, observed a round, white or aluminum colored object moving across the sky from the South to North.
It then veered to the northeast where it disappeared.
Hart estimated the speed of the object at 1,500 mph at an estimated altitude of 35,000'.
Hart estimated the size of the object comparable to a B-29 aircraft.
The other witnesses were Staff sergeant J.D. Denning, and Staff sergeant Harry A. Boggs, both are aircraft mechanics.
The object was in sight from 45 to 60 seconds.
On this same day a similar object was sighted at Davis-Monthan AFB, AZ, at 1:40 p.m. MST.
