Object first seen $ 1 5^{\circ} $ above horizon in the West-Southwest of Lockbourne emitting a ruddy red light which changed to an amber-yellow at intervals not exceeding 1 to 2 seconds. Its size and magnitude were greater than that of any star - a good comparison of the size and magnitude would be a runway light at full intensity viewed from a distance of 500 ft. Shape circular with the exception of a thin wisp of tail extending towards the horizon, the tail being 5 times the diameter of the object in length. For approximately 10 minutes it remained motionless, thereupon it descended to the horizon in about 4", hovered on the horizon in 3", then ascended to its original position in about 3", the course being eliptical, counter clockwise. It then faded and lowered toward the horizon disappearing at 1955. No sound was heard from the object at any time.
Object appeared about 5 miles from Lockbourne, however info received f/Godman Fld and Clinton County Tower plus a relayed report from a pilot over Columbus, O., indicated that they all had observed a similar phenomenon in the same general direction and position at the same time.
RELIABILITY: Witness spent 37 mos in AF in communications work including C. W. and Control Tower Operation. Holds valid CAA Certificate for Control Tower Operator and Aircraft Communications and has worked at Lockbourne in this type of work for over 1-1/2 yrs. Enthusiast of astronomy.
