A former contractor who worked on NASA photographs had claimed that UFOs were airbrushed from the images before release.
The space agency has long been the subject of conspiracy theories concerning UFOs, especially with regard to objects allegedly seen by astronauts during space missions.
One person who repeatedly claimed that not everything was as it seemed was Donna Hare - a former contractor who worked on producing graphics for NASA via Philco Ford Aerospace.
Hare died in 2021, but interviews in which she talked about potential cover-ups at NASA have been circulating the web in recent years and have sparked renewed interest in the topic.
Hare, who worked in the role from 1967 to 1981, claimed on multiple occasions that there was an agenda at NASA to conceal any evidence of UFOs or extraterrestrial visitors.
On one occasion, while working at a restricted photo lab at NASA's Johnson Space Center in Houston, she was shown a photograph of a UFO hovering above some pine trees.
When she queried it, the technician told her that they couldn't provide any details, but indicated that it was standard procedure to airbrush out anything anomalous before the photo made it to the public.
As tends to be the case with such claims, however, it is impossible to know if there is any truth to it or not.
It's possible that she really did have this conversation, but that the lab technician was joking.
It's also possible that the truth is somewhere in-between.
As things stand, the photograph in question has still never seen the light of day.
