aka Hudson Valley Wave (1982–1986)

Over 5,000 sightings of a large, silent, boomerang or triangular object were logged across the Hudson Valley of New York and western Connecticut over four years; J. Allen Hynek led the field investigation in his final years.

phenomenologically-open The Stormville-flyers ultralight formation accounts for a substantial fraction of the 5,000-plus reports; the residue — silent building-sized structure reports, including the 1984 Indian Point nuclear plant overflight — resists it.

Beginning the night of 31 December 1982 over Kent, New York, the Hudson Valley wave produced more than 5,000 reports across Putnam, Westchester, Dutchess, and Orange counties in New York and Fairfield County in Connecticut. The reported object was consistently described as a large, silent V or boomerang shape with multiple lights moving at very low altitude. J. Allen Hynek, founder of the Center for UFO Studies (CUFOS) and former Project Blue Book scientific consultant, personally interviewed hundreds of witnesses during the wave’s final years. He co-authored Night Siege with Philip Imbrogno in 1987, his final book before his death.

J. Allen Hynek, formerly USAF Project Blue Book’s scientific consultant and chair of the Northwestern University Department of Astronomy, personally interviewed hundreds of Hudson Valley witnesses between 1983 and his death in April 1986; Night Siege, published posthumously with Philip Imbrogno, was his final book.

Witnesses to the Hudson Valley sightings included Westchester County police officers, Indian Point nuclear power plant security staff, and (on 24 July 1984) an estimated 300+ motorists who pulled over on the Taconic State Parkway and the Saw Mill River Parkway simultaneously.

Westchester County Airport’s FAA radar logged repeated transponderless returns during the wave window; the FAA’s Eastern Region office formally requested and received Hudson Valley sighting reports from CUFOS in 1984.
