This Central Intelligence Agency memorandum by F. C. Durant reports on the January 1953 meetings of the Office of Scientific Intelligence Scientific Advisory Panel on Unidentified Flying Objects, chaired by Dr. H. P. Robertson. It covers the history of the sessions and the panel members' comments on individual cases, radar interference, instrumentation and an educational program. The panel concluded unanimously that the sightings showed no direct threat to national security. It recommended training and public education to strip UFOs of their special status.

## --a. A centespherical object can readily predict reflections of sunlight without thinking through 60° of one travel.

1000 min-hours of professional and sub-professional time in the preparation of graph plots of individual frames of the film, showing apparent and relative motion of objects and variation in their light intensity. It was the opinion of the P.T.L. representatives that the objects sighted were not birds, balloons or aircraft, were "not reflections because there was no blinking while passing through 60° of arc" and were, therefore, "self-luminous". Plots of motion and variation in light intensity of the objects were displayed. While the Panel Members were impressed by the evident enthusiasm, industry and concern of effect of the P.T.L. to a, they could not accept the conclusions reached. Use of the reasons for this were on follows:

b. Although no data was available on the falladay of birds on polyethylene balloons in bright sunlight, the apparent variations, since and brightness of the objects were considered reasonably to suggest birds, particularly from the Panol viewed a short film showing high reflectivity of neergulls in bright sunlight.

9. P.I.L. description of the objects sighted in the mirror, bluish-white in color would be represented in a series of spoon reflections of sunlight from the surface where the mirror or the reflection would observe other portions of the objects.
