SUl~ARY: At 20zl; LST, 2 Seotc~b~r 1952 sou~ee observed an unidentified tar~et, on the PPI scope of the OCA unit. When first obs--:rvod th'l targo t was 9 miles north or the bield traveling at an estimatad speed or 40 to 60 rnile3 per hour on a heading or 90 , at an altitude or ~000 reet or less (P?.l scope doe~ not give eleva- tions). Durlnc the next hour the number or targets ob~erved varied between one and three. The original target remained on the scope tor 15 minutes while others were visable for a full hour. The tar&ets did not maintain rormatton. Ta,;cets ~ved in various directions but remained in the ~lE quadrant from The range or the targets varied from 16 miles to 1/l, mil9 rrom the rteld. There was no aircraft traffic re~ortod ln tho local area at tha time ot Source was unable to locate the targets by visu~l means. The turgets produced a elearly visable echo. on the ?PI scope about the site of that cau88d by a C-124 aircraft. \'he weather at the time or the sighting w~s: Estimat~d 10,000 broken clouds, Ylalbllit7 7 miles, wind rrom NW at 6 mph, temperature 80 d point 7~ Source atat3d that he was in telenhons contact with the AC'"" unit at Shiroi AB (55 49N 140 OlE) at the time the targets lf!lre oickad up and that th9. radar . obserYers at that bas also picked up the targets in the sarM area. It was the opini ot the source that the targets obse"erl were birds. H~ could not howeYer, acco\D'\t, ror the large echo producsd b7 the objects.
