A U.S. intelligence report says a Soviet biologist linked pilots’ reports of flashes to particles from space.
Aeroflot pilots reported flashes of light during night flights. A Soviet biologist linked them to particles from space, but the report did not establish that those particles caused the flashes.
A November 1976 CIA Foreign Intelligence Information Report (No. 00-B-321/33474-76) on Soviet Aeroflot aerospace medical research. It describes how Aeroflot combats crewmember fatigue through physical conditioning, pre-flight medical testing, and rest facilities (prophylactoria), and details an automated prototype device that measures a pilot's blood pressure, pulse, electrocardiogram, and motor reaction in about three minutes. The report also notes a Soviet radiation biologist's explanation of cosmic-ray phosphenes causing pilots to 'see' light flashes during night flying, and records a brief exchange in which he raised the UFO phenomenon and asked whether something could be coming from outer space. The document is marked 'THIS IS UNEVALUATED INFORMATION.'
Aeroflot pilots reportedly 'see' flashes of light during night flying, which radiation biologist Akoyev explained as cosmic ray particles (phosphenes). Akoyev raised the UFO phenomenon and was told 99 percent of such occurrences trace to natural or man-made phenomena (celestial movement, aircraft, satellites) and the remaining one percent is unexplained, possibly hallucination; he then asked whether something could be coming from outer space.
"Akoyev then asked, "Do you think it is possible...could there be something coming from outer space?""
Speaker: Akoyev
Why it matters: A Soviet radiation biologist explicitly raising the question of extraterrestrial origin in a CIA intelligence report.

"He was told that 99 percent of these occurrences were traceable to either natural or man-made phenomena such as celestial movement, aircraft or artificial satellites, and that the other one percent cannot be explained--possibly an hallucination."
Why it matters: Articulates the standard prosaic-explanation framing of UFO sightings within the report.

Why it matters: Standard intelligence caveat marking the reliability of the report.

The first name of Akutin is redacted/illegible (rendered '[fnu]', first name unknown). Akoyev's first names appear as 'Or[i]nal Georgiyevich' in degraded OCR. Report number is 00-B-321/33474-76 (OCR variants '33474'/'353474'). Manifest notes a more redacted version exists on CIA's public website. UFO content is incidental to a document primarily about aerospace medicine and pilot fatigue testing.
Particles that come from space.
No. The report presents the explanation but describes no test confirming it.
During night flights, pilots for the Soviet airline Aeroflot saw flashes of light. A U.S. intelligence report recorded their accounts and the explanation offered by a biologist who studied radiation.
The report says the pilots saw flashes, but gives no details about what they looked like or what was happening around them. The biologist offered an unusual explanation, linking the flashes to particles from space. That is how the American report described the Soviet research.
Written in November 1976, the report summarized information about medical research conducted by Aeroflot. It also mentioned discussions of unexplained phenomena and the effects of radiation. Among the findings were pilots’ reports of flashes of light during night flights.
Radiation biologist Georgy Akuyev said cosmic particles, or particles that come from space, caused the flashes. The report described them as visible flashes produced by the particles. It was a specific explanation: not just an account of lights, but an attempt to link them to radiation and particles from space.
The document offers no detailed description of what the pilots saw. It does not say whether the flashes appeared within or outside their field of vision, how long they lasted, or whether all the pilots described them in the same way. The report alone cannot tell us whether they all experienced the same thing.
The report presents Akuyev’s remarks as part of its account of Soviet aviation research. It does not explain how the particles could make someone see a flash, nor does it describe any test conducted during the flights to identify the source of the light.
That leaves a gap between the two parts of the story: pilots reported flashes, and a biologist who studied radiation offered an explanation. But the document provides no further evidence connecting the two.
The report describes no test confirming that particles from space caused the flashes. It also provides too little detail to identify what the pilots saw or how the light was produced.
The account leaves us with a single image: a flash during a night flight, and an explanation that points to space.
