Object tracked continuously for Review of this incident by the El.ectronHs a period of six c1nutes. Object was on a Section of ATIC c oncludes that the returp course of 340 deg with only slight deviations was possibly due to interference. This enroute. Alt 1.3,000 ft but accuracy of measur'""et-was concluded be cuas e of the apparent ment questicnable due to brief length time the path of the object, directly approaching ject was detected. F-86 scrambled b~t r a da r the station, and the fact that the contact \-d. t h 1he object \la s lost before a/c target was observed on only the low were airborne. Vi al s earch conducted with beam of t he AN/OPS-1 rada r set. negative results . \leather conditions were not f avorable for anomalous microwave propagation a t time of s i ghting.
