Congarce Air Force Base, South Carolina l, December 1952

I. scription of Incident:

One unidentified object was sighted by radar at Congaree AFB at 03,2 EST
by an AN/MDS-5 radar set. The sighting was strictly electronic, not visual.

| The objectwas sighted 100 miles NE of the radar site, traveling at an esti-
matec speed of 6,000 mph with contact lasting 5 minutes. The weather at the
time consisted of low stratus clouds, no precipitation, and winds KS at 5 mph.

All observers were airmen graduates of radar operator's school with be-

tween two to five years exporience and considered excellent and reliable
sources.

II. Discussion of Incident:

Several past radar sightings of this type have been received by ATIC and
evaluated as probable interference from another radar station, This incident
may fall into this category eventually in that the excessive speeds of 6,000
mph plus the object's tengency to the radar beam's sweep indicate that inter-
ference may—have been present. However, not enough information has yet been
gathered on local weather, temperature and moisture v.s. altitude, so this
incident will be carried as unknown until such information arrives.

III. Conclusion:

Unknown
