During the 1983–1984 Hudson Valley UFO wave, security guards at the Indian Point nuclear power plant on the Hudson River near Peekskill, New York, reportedly watched a large, boomerang-shaped object hover near one of the reactors. The account comes from researcher Philip Imbrogno; no official incident report has been made public.[1][2]
The reports
Imbrogno said guards at the plant saw an object over the site on 14 June and on 24 July 1984, the latter lasting 10 to 15 minutes. Some versions say security systems or computers malfunctioned during the sighting. The account comes mainly from unnamed guards interviewed for the book Night Siege (1987) by Imbrogno, J. Allen Hynek and Bob Pratt, and the number of witnesses and details differ between versions.[1][2]
The Hudson Valley wave
From 1982 to the mid-1980s thousands of people in New York's Westchester, Putnam and Dutchess counties and in Connecticut reported huge, silent formations of lights shaped like a "V" or boomerang. On the same night as the second Indian Point report, residents of nearby Brewster filmed rotating lights. Many sightings were traced to a group of pilots flying light aircraft in tight formation from Stormville Airport, though some witnesses dispute that this explains them all.[1][3]
Official response
The Nuclear Regulatory Commission said it had no record of the sightings, although press clippings about them were found in its files, released later under the Freedom of Information Act.[1][4]
Context
The testimony notes that the NRC grew out of the old Atomic Energy Commission, which had a role in early UFO investigations at nuclear sites. Reports of objects over nuclear power plants and weapons sites, from Indian Point to drone incursions reported at the Palo Verde plant in Arizona in 2019, remain a concern for security officials.[4]
