One morning in January 1981, Mexican pH๏τographer Carlos Diaz pulled into a deserted car park at Ajusco Park near Mexico City. He was on an ᴀssignment for a magazine, and had arranged to meet a journalist who was yet to arrive.

Diaz sat in his car, preparing his camera for the job ahead. Although it was early in the morning, the air was thick with humidity which made even sitting still uncomfortable. Impatiently, Diaz began to look at his watch.

Suddenly, his attention was caught by a strange yellow glow coming from the valley below him. At first he thought it was a forest fire, but, an instant later, the source of light revealed itself to be a large, orange, oval-shaped UFO, slowly hovering about 30 metres from his car.

Unable to believe his eyes, Diaz quickly grabbed his camera. With it resting on his steering wheel, he began frantically firing off sH๏τs. Then, without warning, the whole car began to shake violently.

Diaz got out of the vehicle and took two more pH๏τographs before the craft sped up vertically into the sky, leaving Diaz in a state of shock. This encounter marked the beginning of what was to develop into one of he most fascinating and long-running contactee cases in the history of UFOlogy.

Today, the case remains among a small minority of alledged extraterrestrial encounters to be supported by verified film documentation that has stood up to the scrutiny of a range of experts
