SUNMARY: At 20:15 LST, 2 September 1952 source observed an unidentified | :
tareet on the PPI scope of the GCA unit. When first observed the targot was 9 miles
north of the field traveling at an estimated speed of 0 to 60 miles per hour on a :

tions). During the next hour the number of targets observed varied batween one and

visable for a full hour.
