Rating: 5  


A Hynek Classification of Distant Encounter is usually an incident involving an object more than 500 feet from the witness. At night it is classified as a "nocturnal light" (NL) and during the day as a "daylight disc" (DD). The size of the object or the viewing conditions may render the object in greater detail but yet not qualify the sighting as a Close Encounter which is an object within 500'.

July 29, 1947; Hamilton Field, Calif. (BBU 69)
2:50 p.m. local. Assistant Base Operations Officer Capt. William H. Ryherd and ex-Air B-29 pilot 1st Lt. Ward Stewart saw for unknown length of time two round, shiny, white objects with estimated 15-25 foot diameters, fly 3-4 times the apparent speed of a P-80, also in sight, (or at 750 mph), at 6,000-10,000 ft heading S or SE at 120°. One object flew straight and level; the other weaved from side-to-side like an escort fighter. (Berliner; FOIA; FUFOR Index)
