Dear Mr. Ruiz,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located Sanitized Version of Project Blue Book Case Files on Sightings of Unidentified Flying Objects, 1947 - 1969 in the Records of Headquarters U.S. Air Force (Air Staff) (Record Group 341) pertaining to Project Blue Book. The records were microfilmed as T1206, have been digitized, and are available in the Catalog.
We also located 2 series of motion picture films about UFOs in RG 341. For copies of the DVDs, please contact the National Archives at College Park - Motion Picture (RDSM) via email at firstname.lastname@example.org or order the DVDs via Amazon using the link in the Catalog description.
We suggest that you review NARA’s Project BLUE BOOK - Unidentified Flying Objects website for additional information; and search unidentified flying object | History, Sightings, & Facts Unidentified flying object websites.
We hope this is helpful. Best of luck with your research!
