CIA-UAP-018: Report of Unusual Flying Object Sightings and Attendant Scientific Activity

Released: June 12, 2026

Written by AI from official sources, checked against them before publishingHow we do this

This is a declassified CIA intelligence report from April 1955 about unusual aerial objects reported in Hungary. The information came from a personal letter written by a Hungarian resident to a relative living in the United States. The letter described fast-moving objects that had captured public and scientific attention.

What was in the letter?

The Hungarian correspondent wrote about aerial objects that had been exciting people for several weeks. She described them as moving at an estimated speed of 12,000 kilometers per hour and noted that scientists were actively studying them. She included a sketch showing the suspected path of these objects in relation to Budapest and Moscow.

How did the CIA get this information?

The report came from a naturalized U.S. citizen who received a letter from a niece living in Budapest. The CIA obtained a photostatic copy (an early type of photocopy) of the original Hungarian letter along with an English translation. This was the first time the niece had mentioned such objects in her correspondence.

What does the report say about reliability?

The document is marked as "unevaluated information," meaning the CIA had not yet assessed whether the account was accurate or what it represented. The report simply documents what the letter contained without drawing conclusions about the nature of the objects described.
