◎ Feb-15 Western Japan UFO Incident (Feb. 15, 1966 – Japan) ◎
On February 15, 1966, just after 6:00 p.m., total of five aircraft, three out of them were All Nippon Airways (Viscount 828-JA8210, Boeing 727-JA8206, Friendship-JA8623), one was Japan Airlines (Convair 880-JA8028), and one was Toa Airways (D.H. Hellon-JA6153), succesively encountered a UFO flying at high speeds in blue and intense light in a wide area of western Japan (Tokai, Kansai, Chugoku, Shikoku, and Kyushu) only in twelve minutes.
Reports and inquiries from witnesses at the Osaka International Airport’s CAB, astronomical observatories and meteorological observatories were flooded. Fourteen cockpit crew members, including the pilot, and air traffic controllers from Osaka and Matsuyama airports and the ASDF Miho Base, etc. witnessed the incident from the ground. As soon as the incident occurred, the All Nippon Airways Chitose Sales Office, the Takamatsu Air Security Office of the Civil Aviation Bureau of the Ministry of Transport, and the Toa Airways Air Service Division reported UFO eyewitness information to IUOC (Headquarters of International UFO Observer Corps), which received reports of this UFO incident one after another from the nationwide contact information network. Captain Norio Doi of Toa Airways, who clearly distinguished himself from “astronomical phenomenon,” prepared four special reports detailing the situation at that time and submitted them to IUOC.
This was a remarkable UFO incident, in which both experts of the “sky” and the “ground” witnessed the UFO one after another, which marked the history of Japan and the world aerospace. At the time of this event, Haiopira (Biratori-cho, Saru-gun, Hokkaido, the holy place of the Ainu people) was in the midst of the construction of the historical space site, the Sun Pyramid, where to be held commemorative ceremony for the International UFO Day held on June 24 of the same year, and ambassadors from various countries had been invited.
