Air Force Request to Declassify CIA Material on Unidentified Flying Objects (UFO)

Read from the scan by GLM-OCR; expect the odd misread word.

C. Objects in the Great Falls case were believed to have probably been aircraft, and the bright lights such reflections.

D. There was no valid reason for the attempt to relate the objects in the Tremonton sighting to those in the Great Falls sighting. This may have been due to misunderstanding in their directive. The objects in the Great Falls sighting are strongly suspected of being reflections of aircraft known to have been in the area.

2. The intensity change in the Tremonton lights was too great for acceptance of the P.T.L. hypothesis that the apparent motion and changing intensity of the lights indicated extremely high speed in small orbital paths.

$ \circ $ Apparent lack of guidance of investigators by those familiar with U.F.O. reports and explanations.

A. analysis of light intensity of objects made from duplicate rather than original film. The original film was noted to have a much lighter background (affecting relative brightness of object) and the objects appeared much less bright.

2. Method of obtaining data of light intensity appeared faulty because of unsuitability of equipment and questionable assumptions in making averages of readings.

j. No data had been obtained on the sensitivity of Kodachrome film to light of various intensities using the same camera type at the same lens openings.
