Last year, the Defense Department released a report of its investigation of decades of claims that Washington was hiding what it knew about extraterrestrial life. The report found allegations of a coverup to be baseless.
In fact, a Wall Street Journal investigation reveals, the report itself amounted to a coverup—but not in the way the UFO conspiracy industry would have people believe.
The public disclosure left out the truth behind some of the foundational myths about UFOs: The Pentagon itself sometimes deliberately fanned the flames, in what amounted to the U.S. government targeting its own citizens with disinformation.
Wall Street Journal.
My guess is a that large majority of the recent reports fit into this category.
