✦ AI summary
CIA-UAP-013 is a declassified CIA Information Report (Report No. DO-B-93674) titled "Report of Unusual Flying Object Sightings and Attendant Scientific Activity," dated around March 1955, with information covering November-March 1955. The source is a naturalized US citizen of Russian extraction who corresponds with a niece living in the USSR. In a November 1955 letter, the niece described "strange comets" that kept people in a nervous state for several weeks, describing very fast speeding objects that drew intense scientific attention, with a speed of approximately 12,000 km per hour estimated for these objects. The letter included a sketch showing the formation and suspected flight path of the objects, mailed from Budapest to Moscow. The source noted this was the first time the niece had mentioned such objects in her letters, and a photostatic copy of the original letter (in Russian, with English translation) was placed on file at the CIA Library. The report is marked UNCLASSIFIED for the excerpt but carries NOFORN/limited-dissemination handling restricting distribution to full-time CIA, AEC, and FBI employees within State and Defense channels.
