- The Kenneth Arnold Coordinated SightingThis theory claimed that Kenneth Arnold’s famous June 24, 1947 sighting near Mount Rainier was not an encounter with unknown craft at all, but a controlled test of advanced U.S. technology derived from captured Nazi flying-wing designs. In the most common version, the objects Arnold saw were linked to the Horten brothers’ all-wing aircraft, especially the Ho 229, which was captured by the United States in 1945 and later studied. The theory drew force from several genuine facts: Arnold’s sighting began the modern flying-saucer era, his own sketches and descriptions did not always resemble simple circular disks, and the United States did take possession of advanced German aviation prototypes after the war. The conspiratorial element was the assertion that Arnold had stumbled onto a coordinated domestic test program using Horten-derived aircraft.
- The Howard Hughes InvisibilityThe Howard Hughes Invisibility theory held that Hughes was not merely an eccentric aviation industrialist working on secret aircraft, but was pursuing or had already achieved some form of practical invisibility in aviation, while the government and Hughes’s own companies obscured his real activities by staging or fabricating his public appearances. In one branch of the theory, the invisible object was an aircraft difficult to see, detect, or track. In another, Hughes himself became effectively absent from public life while voice reports, intermediaries, doubles, or carefully managed appearances maintained the fiction of his visibility. The historical basis was broad but suggestive: Hughes founded Hughes Aircraft in 1932, pursued highly secretive military aviation work including the D-2 and XF-11 lineage, and later became one of the most famous recluses in American life. The conspiracy version fused hidden aircraft development with performative public absence.
