The setting was almost excessively beautiful. The trees were still green. Sailboats rested on the lake. Beyond the conference hall, the Italian Alps rose into the autumn sky.<br>Inside, researchers, former government officials and private benefactors gathered to discuss a subject Vallée had pursued longer than almost anyone alive.<br>He was 86 years old.<br>Nearly seven decades had passed since Vallée began recording his thoughts about unidentified flying objects in a private journal. He had started as a young astronomer in France, continued as a computer scientist working alongside J. Allen Hynek, then carried on through a parallel career as a Silicon Valley entrepreneur and venture capitalist. His diaries had followed him through government briefings, alleged crash sites, laboratories, séances, startup meetings, private conversations with intelligence officials and long nights wondering whether the problem he had given his life to could ever be solved.<br>At Lake Maggiore, Vallée presented a case from 1966.<br>Then he went back to his room and prepared to close the record.<br>Forbidden Science 7: Final Report, published May 26, completes a series of journals extending from the earliest years of Vallée’s career through the end of 2025. It is presented as his final volume and his withdrawal from visible research.<br>The title promises a conclusion. It does not deliver one.<br>There is no recovered spacecraft unveiled in its pages. No alien species is identified. No government official explains what has been hidden. Vallée does not even settle on a final theory of what UFOs are.<br>Instead, he ends his career much as he began it: convinced that something real is being reported, equally convinced that nearly everyone explaining it is getting part of the story wrong.<br>That absence of resolution is not a failure of the book. It is its central revelation.<br>After 70 years inside the UFO mystery, Jacques Vallée remains less certain than many people who entered it last week.<br>The man who would not choose a side

To understand Vallée’s importance, it helps to understand the argument he refused to accept.<br>For most of the modern UFO era, the subject has been organized around a false choice. Either unidentified objects are misidentifications, delusions and hoaxes, or they are spacecraft carrying extraterrestrial visitors.<br>The skeptic says there is nothing there.<br>The believer says there are aliens.<br>Vallée came to suspect that both positions were inadequate.<br>His resistance to easy answers made him one of the most influential thinkers in the history of the subject. It also made him unusually difficult to classify. He has defended witnesses whom mainstream scientists dismissed, then challenged UFO believers who took their testimony literally. He has argued that some sightings involve physical objects while insisting that the phenomenon cannot be understood as hardware alone. He has spent decades around intelligence officers and classified programs, yet repeatedly warned that secrecy, rumor and disinformation make government insiders among the least trustworthy sources in the field.<br>In a 2022 profile, Wired described Vallée as a scientist, technologist and investor regarded by his professional colleagues as unusually serious and grounded. He told the magazine that he might be the only ufologist who still did not know what UFOs were. The remark was partly humorous, but it captured his position precisely.<br>Vallée’s answer was not that nothing could be known.<br>It was that the right questions had barely been asked.<br>The night the evidence disappeared

Vallée was born in Pontoise, France, in 1939. His earliest memories were shaped by war. Allied bombing raids targeted the bridges near his hometown during the liberation of France. The first family house he remembered was destroyed.<br>As a young man, he studied mathematics and astronomy. He wrote science fiction and won France’s Jules Verne Prize. He also began reading reports of strange objects seen during the great European UFO wave of 1954.<br>His first books did not begin with fairies, consciousness or interdimensional beings. They began with data.<br>In Anatomy of a Phenomenon, first...
