From 1982 to the mid-1980s thousands of people in New York's Hudson Valley and western Connecticut reported a huge, slow-moving, silent craft shaped like a boomerang or "V", outlined with bright lights. The sightings of 28 June 1984 drew particular attention. Many reports were traced to pilots flying light aircraft in tight formation, though some witnesses and researchers disputed that this explained them all.[1][2]
The sightings
Reports peaked in 1983–1984 in Westchester, Putnam and Dutchess counties and in Fairfield County, Connecticut. Police officers, engineers and commuters on the Taconic Parkway were among the witnesses. The New York Times described witnesses seeing objects said to be the size of a football field, usually in a V shape or a circle, silent and lit with white, red or green lights. On 24 July 1984 residents of Brewster filmed rotating lights. Researcher Philip Imbrogno said guards at the Indian Point nuclear plant saw an object over the plant on 14 June and 24 July 1984; the Nuclear Regulatory Commission said it had no record of this.[1][3]
Investigation
J. Allen Hynek, Imbrogno and journalist Bob Pratt investigated and wrote Night Siege: The Hudson Valley UFO Sightings (1987), which argued that some sightings could not be explained by aircraft; Hynek called the events "absolutely weird".[1][4]
Explanation
Other investigators, including reporters, police and skeptics, found that many sightings were caused by a group of private pilots from Stormville Airport who flew small Cessna aircraft in tight formation at night, arranging and switching their lights so that the "craft" appeared and vanished. Skeptic Brian Dunning wrote that the pilots called themselves "the Martians". Supporters argue that this does not explain every report, especially those describing long periods of silent hovering. The case was featured on Unsolved Mysteries in 1992.[1][2]
