In 1952, a Brazilian press photographer captured what many believe are one of the best UFO photos taken.
On May 7, 1952, at 4:30 PM, journalist Joao Martins and photographer Ed Keffel were on a routine assignment in Barra da Tijuca, Brazil. Suddenly, Martins spotted an object approaching at high speed – flying sideways. He yelled, "Shoot, Keffel!"
In about 60 seconds, Keffel took five incredible photos of a disk-shaped UFO.
Here's why this case is legendary:
The Brazilian Air Force investigated and declared the photos genuine – but kept their report secret until 1959.
The Aerial Phenomena Research Organization (APRO) called it "one of the best (and possibly the best) photographic UFO case on record."
Martins, an engineer with expertise in aircraft and natural phenomena, swore the object matched no known craft or natural event.
Neither man profited financially – they handed the photos to their magazine without any bonus.
The Controversy: Skeptics point to photo #4, claiming shadows on foliage indicate lighting from the right, while light on the object appears from the left. But APRO's Jim Lorenzen countered that the sun never shines from the southwest quadrant in that part of Brazil – and the hillside growth is too complex for clear shadow patterns.
The case was later re-analyzed by the University of Colorado UFO Project (William K. Hartmann), who noted the inconsistency. Yet for many, the photos remain unexplained.
Was this a flying saucer, a hoax, or a misidentified aircraft? Watch the full breakdown – and see the five photos that baffled the Brazilian Air Force.
Comment: Do the shadows prove it's fake, or is the skeptic argument flawed?
