The Hudson Valley and the Silent Triangle

Between 1982 and 1986 the Hudson Valley north of New York City produced several thousand reports of the same thing: a very large triangular or boomerang-shaped object with lights along its edge, moving low, slowly and almost silently. The witnesses were suburban residents, police, and staff at the Indian Point nuclear station. Part of the wave is explained and undisputed: a group of amateur pilots from Stormville airfield flew in formation at night with their lights on as a prank, and never denied it. The argument is whether that covers all of it: several reports describe an object blocking hundreds of metres of sky, which is large for a formation of light aircraft.
