MEMORANDUM FOR: Director of Naval Intelligence

Attention: Op 322Y5

SUBJECT: Interpretation of Movies of Unidentified Flying Objects

1. The attached movies (see Incl. 1) are possibly the best documentary evidence yet obtained on unidentified flying objects. They have been analyzed by an Air Force photographic laboratory. However, it is our desire to obtain an independent analysis by a separate laboratory in order that we may better interpret the implications of these data. For this reason, it is requested that as complete an interpretation as possible be rendered by a Navy activity.

2. Circumstances surrounding the photography are summarized in Inclosure 2. Additional details were requested by messages which are included as Inclosures 3 and 5 and were obtained in the replies attached as Inclosures 4 and 6. With regard to Inclosures 5 and 6, the final footage of film referred to has been detached and returned to CPO Newhouse. However, it was deduced from this portion that Newhouse obtained excellent results while hand-holding the camera; there was almost no camera motion evident. This deduction was applied to the analysis of that portion of the film depicting the motion of the single object which detached itself from the group as explained in Inclosure 2.

3. A list of representative questions for the interpretation is attached as Inclosure 7. These questions are indicative of the type data desired. Any additional data which can be obtained would be most welcome, particularly as concerns the light intensity of the objects, the formations (including three-dimensional renditions, if possible), comments regarding the possibility that the images were caused by aircraft and the conditions which must have prevailed for aircraft to produce such images, etc.

4. It was determined from the Naval Observatory, Washington, D.C. that the position of the sun at the time and location of the photography was 64.5° elevation and 131° azimuth.

5. Your cooperation in satisfying this request at the earliest practicable time is earnestly solicited.
